Investigation of the {sup 3}He wave function by quasielastic scattering
The CE25 experiment, recently completed at the IUCF cooler ring, measured the beam and target analyzing powers and the spin correlation parameter in {sup 3}{tilde H}e({tilde p}, 2p) and {sup 3}{tilde H}e({tilde p}, pn) quasielastic scattering. Polarized protons with incident energies of 200, 300 and 415 MeV were scattered from an metastability-exchange optically pumped polarized {sup 3}He internal target. Quasielastic reactions are expected to be sensitive to the polarization of the nucleons in {sup 3}He. The results provide tests of Faddeev-based calculations, which indicate that the polarization of the {sup 3}He nucleus is carried predominantly by the neutron. The experiment included detection of the quasielastic reactions and of the 3{tilde H}e({tilde p}, p{sup 3}He) and 3{tilde H}e({tilde p}, {pi}{sup +}{alpha}) reactions for polarization and luminosity monitoring. The experimental technique and results of the analysis will be presented.
