Analyzing power of thep→p→π+dreaction at 400 and 450 MeV

Abstract

Analyzing power measurements of the $\stackrel{\ensuremath{\rightarrow}}{p}p\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}d$ reaction have been made at proton bombarding energies of 400 and 450 MeV, over the angular range from 76-119\ifmmode^\circ\else\textdegree\fi{} center of mass. The data at 400 MeV confirm older measurements; no previous data at 450 MeV have been reported. A comparison of these data with theoretical predictions of Niskanen reveals generally good agreement, although the data tend to exhibit slightly greater asymmetry about 90\ifmmode^\circ\else\textdegree\fi{} than predicted by theory.NUCLEAR REACTIONS $\stackrel{\ensuremath{\rightarrow}}{p}p\ensuremath{\rightarrow}d{\ensuremath{\pi}}^{+}$, polarized protons, ${T}_{p}=400 \mathrm{and} 450$ MeV; measured ${A}_{y}(\ensuremath{\theta})$.
