80 MeV positive and negative pions inelastically scattered from targets of ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ and ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ have been studied at laboratory angles between 50° and 120°. Angular distributions are presented for scattering from the 4.44 MeV ($2^{+}$) state in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, the 3.7 MeV ($3^{-}$), 13.4 MeV, and 17.5 MeV states in ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$. The cross sections are compared with distorted wave calculations using potentials obtained from elastic scattering.

NUCLEAR REACTIONS ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$($\pi$,${\pi }^{\prime }$), ${}_{}{}^{40}{}_{}{}^{}\mathrm{C}$($\pi$,${\pi }^{\prime }$), $E=80\mathrm{}$ MeV; measured $\sigma \left(\theta \right)$ for low lying (${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$) and giant resonance (${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$) states; DWBA analysis.
