EFFECT OF SHORT-RANGE NUCLEAR CORRELATIONS ON THE (γ,p) CROSS SECTIONS FOR 208Pb IN A PARTICLE-HOLE MODEL

Abstract

One-proton photodissociation cross sections are studied for the reaction 208 Pb (γ,p)207 Tl at photon energies between 20 and 80 MeV. The transition into the 1g7/2 state of 207Tl is calculated in a particle-hole model with short-range correlations and compared with estimated cross sections based on experimental differential cross sections of Bobeldijk (1995). The short-range correlations are described by Jastrow factors. The correlation factors increase the total cross section. This result is in better agreement with experimental data than calculations without short-range correlations.
