Model Calculation of n + ⁶ Li Reactions Below 20 MeV

Abstract

Based on the unified Hauser–Feshbach and exciton model for light nuclei, the calculations of reaction cross sections and the double-differential cross sections for n + 6Li are performed. Since all of the first-particle emissions are from the compound nucleus to the discrete levels, the angular momentum coupling effect in pre-equilibrium mechanism must be taken into account. The fitting of the measured data indicates that the three-body break-up process needs to be involved, and the pre-equilibrium reaction mechanism dominates the reaction processes. In light nucleus reactions the recoil effect must be taken into account.

Theoretical Model Calculation for d + 8 Li Reaction

“…Becchetti et al [1] made a systematic study of 8 Li radioactive nuclear beams induced reactions at low bombarding energies involving a variety of light and heavy targets, and the experimental data of angular distributions for 8 Li(d, t) 7 Li reaction at incident deuteron energy 3.5 MeV were given. M.J. Balbes et al [2] measured angular distributions of the 8 Li(d, t) 7 Li and 8 Li(d, n) 9 Be reactions at E c.m. = 1.5 to 2.8 MeV using a 8 Li-radioactive-beam technique.…”
