Abstract

We study the heavy-ion collision at sub-barrier energies of {sub 16}O+{sub 144}Sm system using full order coupled-channels formalism. We especially investigate the sensitivity of fusion and quasi-elastic barrier distributions for this system on the coupling radius parameter. We found that the coupled-channels calculations of the fusion and the quasi-elastic barrier distributions are sensitive to the coupling radius for this reaction in contrast to the fusion and quasi-elastic cross section. Our study indicates that the larger coupling radius, i.e., r{sub coup}=1.20, is required by the experimental quasi-elastic barrier distribution. However, the experimental fusion barrier distribution compulsory the small value, i.e., r{sub coup}=1.06.

Effects of anharmonic vibration on large-angle quasi-elastic scattering of {sup 16}O+{sup 144}Sm

Journal Article Zamrun, Muhammad; Hagino, K - Physical Review. C, Nuclear Physics

We study the effects of double octupole and quadrupole phonon excitations in the {sup 144}Sm nucleus on quasi-elastic {sup 16}O+{sup 144}Sm scattering at backward angles. To this end, we use the coupled-channels framework, taking into account explicitly the anharmonicities of the vibrations. We use the same coupling scheme as that previously employed to explain the experimental data of sub-barrier fusion cross sections for the same system. We show that the experimental data for the quasi-elastic cross sections are well reproduced in this way, although the quasi-elastic barrier distribution has a distinct high energy peak which is somewhat smeared in themore »« less

Role of Anharmonic Vibration on Heavy-ion Fusion Reaction and Large Angle Quasi-elastic Scattering of {sup 16}O+{sup 144}Sm

Journal Article Muhammad, Zamrun; Hagino, K - AIP Conference Proceedings

We study the effects of double quadrupole and octupole phonon excitations of {sup 144}Sm nucleus on heavy-ion fusion reaction and large angle quasi-elastic scattering for {sup 16}O+{sup 144}Sm reaction using the coupled-channels approach. We explicitly taken into account the anharmonicites of nuclear vibrations using the sdf-interacting boson model. It is shown that the anhamronicities play an essential role in reproducing the experimental data of the fusion cross section as well as the fusion barrier distribution for this system. Also the quasi-elastic cross section is well reproduced in this way. However, the quasi-elastic barrier distribution has a high distinct peak whichmore »« less

Breakup coupling effects on near-barrier quasi-elastic scattering of {sup 6,7}Li on {sup 144}Sm

Journal Article Otomar, D; Lubian, J; Gomes, P; ... - Physical Review. C, Nuclear Physics

Excitation functions of quasi-elastic scattering at backward angles have been measured for the {sup 6,7}Li+{sup 144}Sm systems at near-barrier energies, and fusion barrier distributions have been extracted from the first derivatives of the experimental cross sections with respect to the bombarding energies. The data have been analyzed in the framework of continuum discretized coupled-channel calculations, and the results have been obtained in terms of the influence exerted by the inclusion of different reaction channels, with emphasis on the role played by the projectile breakup.

Quasi-Elastic Barrier Distribution for the {sup 7}Li+{sup 144}Sm Weakly Bound System

Journal Article Otomar, D; Gomes, P; Lubian, J; ... - AIP Conference Proceedings

We have measured the excitation function of quasielastic and elastic scattering, at backward angles, for a range of energies from below to above the Coulomb barrier, for the {sup 7}Li+{sup 144}Sm system. Barrier distributions were exctracted from these excitation functions by a numerical method. From the theoretical analysis one concluded that the quadrupole and octupole excitations of {sup 144}Sm and the one-neutron transfer (stripping) channel are important reaction processes. Nevertheless, the agreement with the experimental results is poor. The discrepancy is attributed to the {sup 7}Li break-up channel that was not taken into account in the coupling scheme.

Charged particle sub-barrier transfer reactions for {sup 16}O + {sup A}Sm and their influence on the fusion cross section

Journal Article Gomes, P; Maciel, A; Cabezas, R - Bulletin of the American Physical Society

Transfer cross section angular distribution data for the stripping of two protons and one alpha particle are studied for the {sup 16}O + {sup A}Sm systems (A = 144, 148, 150, 152 and 154), at energies slightly lower than the Coulomb barriers and angles up to 0 = 170{degrees}. From a semiclassical formalism, transfer and elastic scattering data, the transfer form factors is derived. For only one of the ten channels studied there are signatures for the interpretation that the transfer reaction mechanism at backward angles, corresponding to small distances, may behave as a multi-step process leading to fusion.
