Polarization observables in the semiexclusive photoinduced three-body breakup of 3He -: art. no. 044002

The photon and He-3 analyzing powers as well as spin correlation coefficients in the semiexclusive three-body photodisintegration of He-3 are investigated for incoming photon laboratory energies E-gamma=12,40, and 120 MeV. The nuclear states are obtained by solving three-body Faddeev equations with the AV18 nucleon-nucleon potential alone or supplemented with the UrbanaIX three-nucleon force. Explicit pi- and rho-meson exchange currents are taken into account, but we also compare to other models of the electromagnetic current. In some kinematical conditions we have found strong effects of the three-nucleon force for the He-3 analyzing power and spin correlation coefficients, as well strong sensitivities to the choice of the currents. This set of predictions should be a useful guidance for the planning of measurements. In addition, we compare our results for two-body He-3 breakup induced by polarized photons with a few existing data.
