Angular distributions of the analyzing powers have been measured for the {sup 3}He({ital {rvec p}},{pi}{sup +}){sup 4}He reaction at proton bombarding energies of 300, 416, and 507 MeV. These results, together with existing measurements at 178, 198, and 800 MeV, provide a comprehensive set of data spanning the region of the {Delta}{sub 1232} resonance. The results are compared with a phenomenological model that incorporates the amplitudes for the {ital pp}{r arrow}{ital d}{pi}{sup +} reaction and calculations from a microscopic ({ital p},{pi}{sup +}) model.
