Potential cluster approach to the description of the 7Li + γ ai p6He reactions

Abstract

Angular distributions for the 6He(p, γ0 + 1)7Li process at the energy Eγ = 40 MeV are calculated within the potential cluster approach. It is shown that the observed cross section is well reproduced when E1 and E2 transitions are taken into account; in this case, unlike the case in the RGM calculations, the dominating mechanism is direct capture to the ground state of the 7Li nucleus. Total cross sections for direct photodisintegration 7Li (γ, p0)6He in the energy interval Eγ = 22–30 MeV are calculated.
