Neutron and Proton Capture by 6Li

Abstract

The 6Li(n, y) and 6Li(p, y) cross sections at low energies are calculated by means of a direct-capture potential model and the results are compared with experimental data. Potential depths chosen to fit 6Li(n, n) and 6Li(n, ex) data are also used for the 6Li + P system. Standard values of the potential parameters and spectroscopic factors give cross sections that are too small for both the (n, y) and (p, y) reactions. However, modified values of these parameters that fit the (n, y) cross section also give good agreement with the (p, y) cross section.
