Inclusive Breakup Cross Sections in Reactions Induced by the Nuclides 6He and 6,7Li in the Two-Body Cluster Model
Abstract
Calculations of inclusive α particle production are performed to interpret reaction experimental data induced by the two-neutron halo 6He and the isotopes 6,7Li on different target nuclei. We have implemented the zero-range post-form DWBA to compute the elastic and nonelastic breakup cross sections. Integrated cross sections, angular distributions and spectra are presented. Projectiles are approximated as two-body clusters, namely 6He as α+dineutron and 6Li (7Li) interpreted as α+deuteron(triton). The S\~ao Paulo optical potential is employed in the calculation of the distorted wave functions for the incident channels, while standard phenomenological interactions are used for the fragment-target interactions. Calculations for 6Li and 7Li furnish a good description of the data, while the reaction involving 6He is found to be a complicated case, where data interpretation is still considered a major obstacle. The present analysis identifies an overall large contribution from inclusive breakup emissions for all the cases studied.
