Abstract
The photon and $^{3}\mathrm{He}$ analyzing powers as well as spin correlation coefficients in the semiexclusive three-body photodisintegration of $^{3}\mathrm{He}$ are investigated for incoming photon laboratory energies ${E}_{\ensuremath{\gamma}}=12,40$, 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 \ensuremath{\pi}- and \ensuremath{\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 $^{3}\mathrm{He}$ 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 $^{3}\mathrm{He}$ breakup induced by polarized photons with a few existing data.
