Abstract

Using a single-particle model for 6Li, electric dipole cross sections for the reactions 6Li(γ, p) 5He and 6Li(γ, n) 5Li have been evaluated in the photon energy range from the respective thresholds to 20 MeV. The interaction between the outgoing nucleon and the rest of the nucleus has in each case been represented by a Saxon-Woods potential, a Coulomb term being added in the (γ, p) case. With potential parameters adapted from optical-model analyses, good agreement has been obtained between the theoretical estimates and experimental data by assuming a rather high percentage of α−d clustering in 6Li.
