Nuclear $\gamma$ rays from 200-MeV ${\pi }^{\pm }$ 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 $\gamma$ ray cross sections were similar for both ${\pi }^{\pm }$. If the interaction were direct with no distortion on a ${\left(1\mathrm{}{f}_{\frac{7}{2}}\right)}^3$ proton configuration, the ${\pi }^{-}$ cross sections would be 1/9 the ${\pi }^{+}$ cross sections.

NUCLEAR REACTIONS ${}_{}{}^{51}{}_{}{}^{}\mathrm{V}({\pi }^{\pm },{\pi }^{\pm \prime }\gamma )$; $E_{\pi }^{}{}_{}{}^{\pm }=200\mathrm{}$ MeV; detected $\gamma \text{'}\mathrm{s}$; Ge(Li); measured 90° $\sigma$ for 320, 930, 1610, and 2700 keV ${}_{}{}^{51}{}_{}{}^{}\mathrm{V}$ levels.
