Abstract

The ( $\vec{p}, t$ ) and ( $\vec{p}, {}^{3}{He}$ ) reactions have been induced on ${}^{16}O$ , ${}^{15}N$ , and ${}^{13}C$ targets by polarized protons of 43.8 or 49.6 MeV. Relative differential cross sections and analyzing powers were measured for 32 transitions and compared with zero-range distorted-wave Born-approximation calculations employing Cohen and Kurath wave functions. Although good results for differential cross sections were obtained, attempts to fit analyzing powers were less successful. In general ( $\vec{p}, t$ ) results gave better agreement than ( $\vec{p}, {}^{3}{He}$ ), ground state transitions better than those to excited states, and transitions to analog states better than more complex transitions.
