Abstract

Analyzing powers for the ${}^{4}{He}$ ( $\vec{p}$ , $2 p$ ) ${}^{3}H$ reaction have been measured at 250 and 500 MeV for three pairs of quasifree angles, i.e., 55°-25°, 50°-30°, and 45°-35°. The range of recoil momenta covered is from zero to 150 MeV/c. The data have been compared with distorted-wave impulse approximation predictions. In general only reasonable agreement is obtained, pointing to deficiencies in the distorted wave impulse approximation even at low recoil momenta.
