Abstract

The analyzing power $A$ of the reaction $T (p, n) {}^{3}{He}$ has been measured at 45° c.m. from 1.5 to 12 MeV with a polarized proton beam. A comparison with existing data for the neutron polarization $P$ shows that $P$ and $A$ have similar excitation functions at this angle, but that the magnitude of $P$ is generally less than that of $A$ . While the $R$ -matrix formalism does not require exact equality between $P$ and $A$ , we do not have at present a successful explanation of the observed differences.
