Abstract

The first measurement of the reaction He3(,p)X using linearly polarized photons is reported. Cross sections and beam-polarization asymmetries for plab=60°100°and E=195304 MeV are compared with a microscopic calculation which includes one-, two-, and three-nucleon absorption mechanisms. One- and two-nucleon absorption alone fails to describe the data at low proton momenta. The inclusion of three-nucleon absorption significantly improves the comparison with the measured cross sections. However, some features of the asymmetry distributions are not explained.
