Abstract
Differential cross sections for the He-3(gamma,pd) reaction at photon energies between 200 and 800 MeV at all proton c.m. angles between 35- degrees and 145-degrees have been measured using the tagged photon bea m facility of the 855 MeV MAMI accelerator in Mainz. Reaction products were detected using the large acceptance detector DAPHNE. The results confirm the rapid decrease of forward-angle cross sections with incre asing E(gamma) whilst at backward angles, aided by the high precision of the measurement, we can see a clear enhancement in the angular dist ribution which is a possible signature of three-body mechanisms.
