Proton-Proton Elastic Scattering between 6 and 10 MeV

Abstract

Proton-proton elastic scattering angular distributions have been measured at 6.141-, 8.097-, and 9.918- MeV laboratory energy, in an experiment designed to achieve an absolute accuracy better than 1%. Phaseshift analyses have been performed using $S$, split $P$, and $D$ waves. The $P$-wave splitting was assumed to be dominated by (a) a central-plus-tensor interaction or (b) a central-plus-spin-orbit interaction. In both cases, the $P$-wave splitting was kept small, a condition imposed by the small polarizations measured in this energy range.
