Abstract

Complete and incomplete fusion cross sections for the 9 Be + 144 Sm reaction have been measured at near-barrier energies, using the delayed X-ray detection technique. At above-barrier energies these show a suppression of complete fusion for this weakly bound projectile on an intermediate mass target. The suppression factor, attributed to 9 Be break-up, was deduced from a comparison of complete fusion yields with coupled-channels calculations, and appears consistent with measured incomplete fusion product yields. At ∼ 10%, it is considerably smaller than the value of ∼ 30% previously found for a 208 Pb target. Simultaneous measurements of elastic and inelastic scattering permit a clearer picture of the reaction mechanisms.

Fusion cross sections for 7Li + 11B and 9Be + 9Be reactions at low energies
Anjali Mukherjee

1997

The partial cross sections for the 7Li ÷ HB and 9Be + 9Be reactions below and above the Coulomb barrier energy have been determined from the cross sections of the characteristic y-rays of the residual nuclei and using the branching factor o'~/O'ch obtained from the statistical model calculations. The fusion cross sections obtained from the sum of these partial cross sections are found to be equal to the total reaction cross sections upto an energy well above the Coulomb barrier energy for the 9Be ÷ 9Be reaction. For the 7Li ÷ ~B reaction, however, the fusion cross sections are found to be less than the total reaction cross sections at energies not much above the Coulomb barrier. The maximum fusion cross sections for the 7Li ÷ ltB and 9Be + 9Be reactions are found to be 66% and ~ 81% of the total reaction cross sections at Ec.m. = 2Be (where Bc is the Coulomb barrier energy), respectively.

Complete and incomplete fusion in 9Be+124Sn system
Anil Raghav

Proceedings in Radiochemistry, 2011

Complete and incomplete fusion cross-sections for the 9Be+124Sn system have been measured around the Coulomb barrier energies (E lab C.B=28 MeV) using the on-line gamma ray detection technique. The complete fusion cross-sections of this system have been compared with the two stable projectiles on the same 124Sn target to provide information on the projectile dependence. The brief comparison of the present 9Be+124Sn data with a comprehensive and recent study of the neighbouring system 9Be+144Sm is also given.

Detailed determination of the nuclear fusion radius by a simultaneous optical model calculation of elastic scattering and fusion cross sections in reactions involving weakly bound projectiles
Ivan Padron

Physical Review C, 2007

Within the optical model for direct reactions, simultaneous calculations of elastic scattering, complete fusion, and total reaction cross sections for energies around the Coulomb barrier are presented for reactions involving the weakly bound projectile 9 Be on 64 Zn. Volume (W F) and surface (W DR) Woods-Saxon optical potentials are used such that the former is responsible only for complete fusion reactions while the latter for all direct reactions plus incomplete fusion. Simultaneous fits can be obtained with several sets of potential parameters, but if we impose the condition that the strength of W F is smaller than the strength of W DR at the tail region of the potential (this condition is discussed in detail), then values are required for r F and r DR of around 1.6 and 1.7-1.9 fm, respectively. These values are much larger than those frequently used in barrier penetration model calculations. Through the energy dependence of the real and imaginary parts of the polarization potentials, we show that the usual threshold anomaly does not show up for this system, but instead there is evidence of the presence of a breakup threshold anomaly.

STUDY OF FUSION REACTIONS INDUCED BY WEAKLY BOUND NUCLEI
Abdelghani A Elsayed

Fission and evaporation cross sections were measured in a broad range of energies near the Coulomb barrier and up to 180 MeV in the reactions 46He+U'9Bi and 'Li+2"8Pb. The secondary 4.hHe beams were produced using the beam-transport line of the U400M accelerator at FLNR, JINR. The experimental fusion and fission excitation functions obtained for the different reactions 4He+2"9Bi, 'He+*"'Bi and 7Li+Z'1XPb and leading to the same composite nuclei 2".2'5At were analyzed using the PACE-4 and CC codes from the point of view of the fusion reaction mechanism induced by weakly bound nuclei. The comparison between the fission and fusion excitation functions for the three reactions 46He+211yBi and 7Li+2"8Pb has shown that they are the same within the experimental error for a broad range of energy.

Fusion versus Breakup: Observation of Large Fusion Suppression for 9Be+208Pb
Roberto Leal Dos Anjos

Physical Review Letters, 1999

Complete fusion excitation functions for 9 Be + 208 Pb have been measured to high precision at near barrier energies. The experimental fusion barrier distribution extracted from these data allows reliable prediction of the expected complete fusion cross-sections. However, the measured cross-sections are only 68% of those predicted. The large cross-sections observed for incomplete fusion products support the interpretation that this suppression of fusion is caused by 9 Be breaking up into charged fragments before reaching the fusion

Suppression of complete fusion due to breakup in the reactions B10,11+Bi209
L. Gasques

Physical Review C, 2009

Above-barrier cross sections of α-active heavy reaction products, as well as fission, were measured for the reactions of 10,11 B with 209 Bi. Detailed analysis showed that the heavy products include components from incomplete fusion as well as complete fusion (CF), but fission originates almost exclusively from CF. Compared with fusion calculations without breakup, the CF cross sections are suppressed by 15% for 10 B and 7% for 11 B. A consistent and systematic variation of the suppression of CF for reactions of the weakly bound nuclei 6,7 Li, 9 Be, 10,11 B on targets of 208 Pb and 209 Bi is found as a function of the breakup threshold energy.

Influence of projectile breakup on fusion with 159Tb target; Measurement of CF and ICF cross sections
Mukesh Pradhan

Proceedings of VI European Summer School on Experimental Nuclear Astrophysics — PoS(ENAS 6), 2013

To study projectile breakup effects on fusion reactions with 159 Tb target, the measurements of complete fusion (CF) cross sections for the 11 B+ 159 Tb, 10 B+ 159 Tb, 7 Li+ 159 Tb and 6 Li+ 159 Tb reactions at energies around their respective Coulomb barriers are highly desirable. The four reactions, in fact, show that at below-barrier energies, the measured CF cross sections are enhanced compared to the predictions of the 1D BPM calculations and at above-barrier energies for the 10 B+ 159 Tb, 7 Li+ 159 Tb and 6 Li+ 159 Tb reactions, CF cross sections are suppressed by projectile breakup effects with respect to the coupled channels (CC) calculations. The CF cross section suppression effects are correlated with the α-breakup threshold of the projectiles. Also, the measured incomplete fusion (ICF) cross sections for the 10 B+ 159 Tb, 7 Li+ 159 Tb and 6 Li+ 159 Tb reactions show that the ICF process, with α-emitting channel, is the dominant contributor and this observation is found to be consistent with the Q-values of the reactions.

Observation of incomplete fusion reactions at l < l crit
Abhishek Yadav

2014

In order to understand the presence of incomplete fusion at low energies i.e. 4-7MeV/nucleon & also to study its dependence on various entrance-channel parameters, the two type of measurements (i) excitation function for 12 C+ 159 Tb, and (ii) forward recoil ranges for 12 C+ 159 Tb systems have been performed. The experimentally measured excitation functions have been analyzed within the framework of compound nucleus decay using statistical model code PACE4. Analysis of data suggests the production of xn/pxn-channels via complete fusion, as these are found to be well reproduced by PACE4 predictions, while, a significant enhancement in the excitation functions of α-emitting channels has been observed over the theoretical ones, which has been attributed due to the incomplete fusion processes. Further, the incomplete fusion events observed in case of forward recoil range measurements have been explained on the basis of the breakup fusion model, where these events may be attributed to the fusion of 8 Be and/or 4 He from 12 C projectile to the target nucleus. In the present work, the SUMRULE model calculations are found to highly underestimate the observed incomplete fusion cross-sections which indicate that the ℓ-values lower than ℓ crit (limit of complete fusion) significantly contribute to the incomplete fusion reactions.

Reaction mechanisms for weakly-bound, stable nuclei and unstable, halo nuclei on medium-mass targets
A. Diaz-Torres

Nuclear Physics A, 2010

An experimental overview of reactions induced by the stable, but weakly-bound nuclei 6 Li, 7 Li and 9 Be, and by the exotic, halo nuclei 6 He, 8 B, 11 Be and 17 F on medium-mass targets, such as 58 Ni, 59 Co or 64 Zn, is presented. Existing data on elastic scattering, total reaction cross sections, fusion processes, breakup and transfer channels are discussed in the framework of a CDCC approach taking into account the breakup degree of freedom.

Physical Review C, 2005

The total fusion cross section for the 9 Be + 27 Al system has been measured at energies close and above the Coulomb barrier. Reaction cross sections for this system were derived from elastic scattering data, and the breakup-plus-transfer-channel cross sections were estimated from the difference between these data and measured cross-section fusion.

Fusion cross sections for theBe9+Sn124reaction at energies near the Coulomb barrier
Anil Raghav

Physical Review C, 2010

The complete and incomplete fusion cross sections for 9 Be+ 124 Sn reaction have been deduced using the online γ-ray measurement technique. Complete fusion at energies above the Coulomb barrier was found to be suppressed by ∼28% compared to the coupled-channels calculations and is in agreement with the systematics of L. R. Gasques et al. [Phys. Rev. C 79, 034605 (2009)]. Study of the projectile dependence for fusion on a 124 Sn target shows that, for 9 Be nuclei, the enhancement at below-barrier energies is substantial compared to that of tightly bound nuclei.

Proposal to the ISOLDE and Neutron Time-of-Flight Committee Fusion hindrance at sub-barrier energies for weakly bound nuclei on heavy targets : the 8 B + 208 Pb case May 18 , 2017
M. La Commara

2017

We propose a study of the B + Pb system at the sub-Coulomb energy of 43 MeV via measurements of the elastic scattering and Be production cross sections. The main goal of this work is to answer a fundamental question concerning the competition between fusion and direct channels below the barrier for a proton halo nucleus like B incident on a heavy target. It is believed from phenomenological predictions that for weakly bound nuclei incident on heavy targets the direct channels exhaust most of the total reaction cross section for incident energies below the Coulomb barrier, with important consequences for both fusion and various astrophysical problems. In this context the sub-barrier breakup and elastic scattering will be investigated for a global understanding of this issue and the relevant channel coupling effects. In addition the elastic scattering measurement will address another fundamental question: how far does the elastic scattering for proton halo nuclei deviate from Rutherfo...

Suppression of fusion by breakup: Resolving the discrepancy between the reactions ofBe9withPb208andBi209
Madhumita Dasgupta

Physical Review C, 2010

Complete fusion cross sections for 9 Be incident on 208 Pb and 209 Bi have been measured at energies greater than the fusion barrier to investigate the large differences in their reported complete fusion cross sections. Relative xn and fission cross sections are in good agreement. Thus, it is concluded that the differences arise from errors in absolute normalization in the previous measurements. The present measurements show that the above-barrier complete fusion cross sections for the reactions of 9 Be with 209 Bi and 208 Pb are very similar, which resolves the previously observed anomaly. Complete fusion for the reaction of 9 Be with 209 Bi is found to be suppressed by ∼32% compared to the expectations of a single-barrier penetration model, which is in close agreement with the value previously determined for the reaction with 208 Pb.

Dominance of direct reaction channels at deep sub-barrier energies for weakly bound nuclei on heavy targets: The case B8+Pb208
Angel-Miguel Sanchez-Benitez

Physical Review C

We report the first evidence of breakup dominance at deep sub-barrier energies for the proton halo nucleus 8 B on a heavy target. Angular distribution measurements of the 8 B breakup fragment, 7 Be, on lead were performed at the TwinSol facility of the University of Notre Dame at a beam energy of 30 MeV, 58% of the Coulomb barrier and corresponding to a distance of closest approach of 20.5 fm. The 7 Be yield was observed in two double sided silicon strip detector telescopes symmetrical to the radioactive beam and normalized using the 8 B Rutherford scattering. The results are in excellent agreement with continuum discretized coupled channel calculations with a total breakup cross section (326 ± 84) mb. This is found to exhaust all of the total reaction cross section for the system 8 B + 208 Pb, possibly prohibiting a fusion enhancement. This finding is expected to give more insight to the puzzle of fusion suppression at deep sub-barrier energies with possible major consequences on nuclear astrophysics.

    Fusion of Li with ¹Tb at near-barrier energies
    Prasad Basu

    Physical Review C, 2011

    Complete and incomplete fusion cross sections for 6 Li+ 159 Tb have been measured at energies around the Coulomb barrier by the γ-ray method. The measurements show that the complete fusion cross sections at above-barrier energies are suppressed by ∼34% compared to the coupled channels calculations. A comparison of the complete fusion cross sections at above-barrier energies with the existing data of 11,10 B+ 159 Tb and 7 Li+ 159 Tb shows that the extent of suppression is correlated with the α-separation energies of the projectiles. It has been argued that the Dy isotopes produced in the reaction 6 Li+ 159 Tb, at below-barrier energies are primarily due to the d-transfer to unbound states of 159 Tb, while both transfer and incomplete fusion processes contribute at above-barrier energies.

    Projectile breakup dynamics for 6Li + 59Co : Kinematical analysis of $ \alpha$ - d coincidences
    A. Diaz-Torres

    The European Physical Journal A, 2010

    A study of the kinematics of the α-d coincidences in the 6 Li + 59 Co system at a bombarding energy of E lab = 29.6 MeV is presented. With exclusive measurements performed over different angular intervals it is possible to identify the respective contributions of the sequential and direct projectile breakup components. The angular distributions of both breakup components are fairly well described by the Continuum-Discretized Coupled-Channels framework (CDCC). Furthermore, a careful analysis of these processes using a semiclassical approach provides information on both their lifetime and their distance of occurrence with respect to the target. Breakup to the low-lying (near-threshold) continuum is delayed, and happens at large internuclear distances. This suggests that the influence of the projectile breakup on the complete fusion process can be related essentially to the direct breakup to the 6 Li high-lying continuum spectrum.

    To study the conditions leading to the appearance of the threshold anomaly in systems involving weakly bound projectiles we measured elastic scattering cross sections for the 7 Li + 27 Al system at ten different bombarding energies. The results were exhaustively analyzed using different optical model potentials. The similar behavior observed in all these analyses allows us to conclude that no threshold anomaly is found for the present system.

    Comprehensive study of reaction mechanisms for theBe9+Sm144system at near- and sub-barrier energies

    The delayed x-ray detection technique was used to measure complete and incomplete fusion cross sections for the 9 Be + 144 Sm reaction at sub-and near-barrier energies. Elastic and inelastic scattering for this system were also measured. Reaction cross sections were derived and the transfer cross sections of one neutron were calculated. The suppression of complete fusion above the barrier, of the order of 10%, is attributed to 9 Be breakup and is considerably smaller than the value of 30% found for the 9 Be + 208 Pb system.
