Investigation of the {sup 3}He wave function by quasielastic scattering
The CE25 experiment has measured beam and target analyzing powers, and spin correlation parameters in {sup 3}He (p,2p) and {sup 3}He (p,pn) quasielastic scattering using a polarized internal target at the IUCF Cooler storage ring for incident beam energies of 200, 300 and 415 MeV. Faddeev calculations predict that approximately 90% of the nuclear spin of {sup 3}He is carried by the neutron. This suggests that polarized {sup 3}He can serve as an effective polarized neutron target. Quasielastic scattering from {sup 3}He provides a test of these predictions. Previously published results from this experiment at 200 MeV indicate that with the proper choice, of kinematics, in particular sufficiently large momentum transfer, there is agreement between experiment and simple PWIA theory. The data at 300 and 415 MeV will provide addtional, tests of these results and indicate any energy dependence. This information is of considerable importance to electron scattering experiments which intend to use polarized {sup 3}He targets to measure the neutron spin structure functions. A description of the experiment and the recent results will be presented and compared, to the 200 MeV results.
