Neutron capture by light nuclei at astrophysical energies

Abstract

Within the potential cluster model with the forbidden states and an orbital\nstates classification according to the Young diagrams the possibility of\ndescription of experimental data for the total cross-sections of radiative\nn15N-capture at energies from 25 to 370 keV was considered. It was shown that\nonly on basis of the E1-transitions from the different states of\nn15N-scattering to the ground state of 16N nucleus in n15N-channel it is well\nsucceed to explain the value of the total cross-sections in the considered\nenergy range and to prognosticate its behavior at energy E 1 eV. These\ncross-sections at energies E 10 keV are approximated by the simple analytical\nform.\n
