Polarization ofHe3Elastically Scattered fromHe4

Abstract

The polarization of ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ nuclei elastically scattered from ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ has been measured. Absolute polarization values are determined from three asymmetries measured at appropriate energies and angles using double-scattering techniques. A polarization angular distribution at 13-MeV ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ energy indicates general agreement with previously reported phase shifts.
