Abstract

Cross sections for single-photonucleon emissions from 7Li have been measured for photon energies in the range 60–120 MeV by detecting the recoiling residual nuclei following excitation with bremsstrahlung radiation of end-point energies 140 and 155 MeV. Measurements of the 7Li(e, 6Li)e'p and 7Li(e, 6He)e'n cross sections were also made at the same electron energies. A significant difference between the ratio of electron- and bremsstrahlung-induced yields for proton and neutron emission is observed. The results are compared to a modified quasi-deuteron model and a simple direct-knockout model in which recoil terms are included.
