Pion inelastic scattering to low-lying states inC12andCa40

Pion inelastic scattering at 180 MeV from the low-lying collective states of ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ and ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ is analyzed using distorted-wave impulse approximation calculations with no free parameters and transition densities obtained from electron scattering. These calculations adequately reproduce the pion scattering data. No significant ${\pi }^{+}$ vs ${\pi }^{-}$ differences are observed at low-momentum transfers.
