Direct ( pi +,pd) cross sections for light nuclei.

Abstract

The angular distributions of the inclusive (${\ensuremath{\pi}}^{+}$,pd) cross section were measured for $^{6}\mathrm{Li}$, $^{7}\mathrm{Li}$, and C at ${T}_{\ensuremath{\pi}}$=70, 130, and 165 MeV over a wide angular range. They were found very similar to that of the \ensuremath{\pi}${+}^{3}$H${(}^{3}$He)\ensuremath{\rightarrow}N+d reaction at the low-momentum-transfer region, especially for Li isotopes. However, at the higher-momentum-transfer region, slight peaks which were not expected in the \ensuremath{\pi}${+}^{3}$H${(}^{3}$He)\ensuremath{\rightarrow}N+d were observed.
