Depolarization Parameter in Proton-Proton Scattering at 213 MeV

Abstract

The depolarization parameter, $D$, in $p-p$ scattering at 213 MeV has been measured over the angular range 30-90° c.m. The results have been included in the modified phase-shift analyses performed by MacGregor et al. and by Signell, which have yielded a unique phase-shift set for $p-p$ interaction at this energy. The results of the experiment are also compared with the predictions by the semiphenomenological potentials of Bryan and of Hamada.
