Direct Photodisintegration of 13C below 17 MeV. Reaction 13C(γ,n) 12C

Abstract

A nuclear model where the single-particle states of the valence neutron are vector coupled to the ground (0+) and first excited (2+) 12C-core states, is considered. The model is applied to calculate total photodisintegration cross sections of the reaction 13C(γ, n)12C for energies below the Giant dipole resonance. The radial wavefunctions in initial- as well as final states are of the Saxon-Woods type.
