Photodisintegration of the 7Li nucleus through the n6Li channel in the potential cluster model

The photodisintegration of the 7Li nucleus through the n6Li channel is considered on the basis of a potential two-cluster model. Intercluster-interaction potentials involve forbidden states and reproduce the phase shifts of low-energy elastic scattering that are obtained by the resonating-group method. The proposed model is shown to describe the total cross section for photodisintegration in the energy range under consideration.
