Abstract

The reaction B(γ,p) has been studied using tagged photons of mean energies E = 57.6 and 72.9 MeV. Angular distributions and derived single-particle momentum distributions for protons leading to the ground state of Be and higher excited states are compared to various calculations made using model parameters constrained by B(e, e′ p) Be and Be(p, p′)Be measurements. The effects of varying final-state interactions (including channel couplings) and meson exchange currents are considered. A sizable discrepancy between direct-knockout calculations and the experimental results is observed. If meson exchange currents are included in an approximate fashion, a good description of the B(γ,p)Be data is found.
