Proton-induced nucleon knockout from polarized 3He at 290 MeV

Abstract A novel polarized 3 He gas target has been used to measure spin observables for ( p ,2 p ) and ( p , pn ) nucleon knockout in quasielastic kinematics at 290 MeV. Comparisons with PWIA calculations show the importance of rescattering corrections, especially for neutron knockout and the target-related asymmetry A 0 n . The A nn ( p ,2 p ) results agree with the PWIA and qualitatively indicate the effects of spin momentum distributions of protons in 3 He as predicted by Faddeev calculations.
