THE REACTION 8 Li(n,γ) 9 Li AT ASTROPHYSICAL ENERGIES AND ITS ROLE IN PRIMORDIAL NUCLEOSYNTHESIS

Abstract

The possibility of describing available experimental data for the total cross sections of neutron radiative capture on 8 Li at thermal and astrophysical energies was considered within the framework of the modified potential cluster model with the state classification of nuclear particles according to the Young tableaux. Our approach allows one to transmit available data in the energy range 0.1–1.0 MeV quite well, and predicts the behavior of the total cross sections at super-low energies, down to 25.3 × 10 −9 MeV.
