Study of the Spin Dependent 3HE-NUCLEUS Interaction at 450 Mev

Differential cross sections and induced polarizations of ³He+¹²C, ⁵⁸Ni, and ⁹⁰Zr elastic scattering were measured at E<INF>3_He</INF> = 450 MeV. This is the first measurement of the polarization for ³He scattering at intermediate energies. The optical potential parameters including the spin-orbit potential were determined with small uncertainties. The volume integrals per nucleon of the potentials were investigated for ³He and their energy dependence showed the similar behavior to that for protons at intermediate energies. The single folding calculations were compared with the data. The real central and spin-orbit parts of the folded potentials had to be reduced by a few tens of percent in order to reproduce the experimental results.
