The spin dependent momentum distributions of the neutron and proton in 3He

The spin asymmetries in the momentum distributions of the neutron and proton in 3He are obtained from a Faddeev calculation of the ground state. Both two- and three-body configurations are found to be important. Using a PWIA model and measurements of the spin asymmetries in 3&( j?,2p) and 3s( j?',pn) quasielastic scattering at 197 MeV the asymmetries in the momentum distributions are experimentally determined. Good agreement between theory and experiment is found up to initial nucleon momenta of 300 MeV/c.
