Hearrow3(p,p)3He analyzing powers between 25 and 35 MeV

A polarized ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ target, which uses conventional optical pumping with ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ discharge lamps, has been used for the measurement of ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ analyzing powers $A_y$(θ) at energies of 25.0, 30.0, 32.5, and 35.0 MeV. The statistical uncertainties in the data are on the order of 0.03; the systematic uncertainty is estimated to be 0.05. These data are compared with fits and predictions from various phase shift analyses.
