Abstract

Angular distributions of the analyzing power of the reaction ${}^{3}H (\vec{p}, n) {}^{3}{He}$ have been measured at proton energies of 6.00, 9.96, and 13.55 MeV. These data are compared with available neutron-polarization data for the same reaction on a point-by-point basis and by means of associated Legendre-polynomial coefficients. In contrast to the comparison below 4 MeV, no significant difference exists above 6 MeV between the two observables at the same energies and angles. The data are also compared with $R$ -matrix calculations based on the parameter sets of Werntz and Meyerhof. The previously reported excitation function for the analyzing power at $θ_{c . m .} = 45^{\circ}$ from 1.5 to 12 MeV is further documented.
