Radiative neutron capture by 2H, 7Li, 14C, and 14N nuclei at astrophysical energies

Abstract

The possibility of describing experimental data on the total cross sections for the n2H, n7Li, n14C, and n14N radiative-capture processes within the potential cluster model involving forbidden states and their classification according to Young’s tableaux is considered. It is shown that this model and the methods used here to construct potentials make it possible to describe correctly the behavior of the experimental cross sections at energies between 5 to 10 meV (5 × 10−3–10 × 10−3 eV) and 1 to 15MeV.
