Effect of the exit reaction channels onLi6+O18elastic scattering

Abstract

The most pronounced reaction channels in the 6Li + l80 system were studied by means of the continuumdiscretized coupled-channel and coupled-reaction-channel methods to investigate their effects on the elastic scattering. It is shown that, whereas breakup coupling provides no contribution to the observed rise in the backward-angle elastic scattering angular distribution, coupling to the single-neutron pickup alone enhances the elastic scattering cross section in this region by up to two orders of magnitude.

Description of elastic scattering for 7Li-induced reactions on 1p-shell nuclei*

“…< Furthermore, some experimental data of the elastic scattering angular distributions for the 7 Li + 13 C system are available [26,31,34]. Comparisons between the calculations and these data are presented in Fig.…”

“…Nuclear reactions of 6,7 Li on light targets are more complicated than those for heavy targets, such as the reactions of 6,7 Li induced 1p-shell nuclei. Complicated reaction dynamics are involved, i.e., strong collective excitations, breakup, and transfer reactions [10][11][12][13]. Some phenomenological optical potentials (POPs) of 7 Li induced 1p-shell nuclei have been realized.…”

“…The goal of this work is to obtain a GPOP describing the elastic scattering of 7 Li on 1p-shell nuclei. To achieve this, existing experimental data of elastic scattering angular distributions are simultaneously considered and fitted for 7 Li projectile on 9 Be, 10 B, 11 B, 12 C, 13 C, 15 N, and 16 O nuclei from 4.5 to 131.8 MeV. While for the reaction of 7 Li + 7 Li, the potential is searched separately from the other 1p-shell nuclei.…”
