Differential cross sections for the 3He(γ,pd) reaction at photon energies between 200 and 800 MeV at all proton c.m. angles between 35° and 145° have been measured using the tagged photon beam 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 increasing Eγ whilst at backward angles, aided by the high precision of the measurement, we can see a clear enhancement in the angular distribution which is a possible signature of three-body mechanisms.

Abstract
Differential cross sections for the 3He(γ,pd) reaction at photon energies between 200 and 800 MeV at all proton c.m. angles between 35° and 145° have been measured using the tagged photon beam 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 increasing Eγ whilst at backward angles, aided by the high precision of the measurement, we can see a clear enhancement in the angular distribution which is a possible signature of three-body mechanisms.File in questo prodotto:
