Abstract

We report measurements of spin correlations and analyzing powers in He3(p, 2p) and He3(p, pn) quasielastic scattering as a function of momentum transfer and missing momentum at 197 MeV using a polarized internal target at the Indiana University Cyclotron Facility Cooler Ring. At sufficiently high momentum transfer we find He3(p, pn) spin observables are in good agreement with free p-n scattering observables, and therefore that He3 can serve as a good polarized neutron target. The extracted polarizations of nucleons in He3 at low missing momentum are consistent with Faddeev calculations.
