Nuclear gamma rays fromV51levels populated by 200 MeVπ±inelastic scattering

Abstract

Nuclear $\ensuremath{\gamma}$ rays from 200-MeV ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ inelastic scattering on $^{51}\mathrm{V}$ were measured. Observed were $^{51}\mathrm{V}$ levels at 0.32, 0.93, 1.61, 1.81, and 2.70 MeV $\ensuremath{\gamma}$ ray cross sections were similar for both ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$. If the interaction were direct with no distortion on a ${(1{f}_{\frac{7}{2}})}^{3}$ proton configuration, the ${\ensuremath{\pi}}^{\ensuremath{-}}$ cross sections would be 1/9 the ${\ensuremath{\pi}}^{+}$ cross sections.NUCLEAR REACTIONS $^{51}\mathrm{V}({\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}},{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}\ensuremath{'}}\ensuremath{\gamma})$; $E_{\ensuremath{\pi}}^{}{}_{}{}^{\ifmmode\pm\else\textpm\fi{}}=200$ MeV; detected $\ensuremath{\gamma}'\mathrm{s}$; Ge(Li); measured 90\ifmmode^\circ\else\textdegree\fi{} $\ensuremath{\sigma}$ for 320, 930, 1610, and 2700 keV $^{51}\mathrm{V}$ levels.
