Abstract
Data for inelastic pion scattering from at =164 MeV, exciting the lowest , , and states, were analyzed by distorted-wave impulse approximation and coupled-channel calculations using transition densities derived from shell model calculations. Coupled-channels effects were found to be relatively unimportant for the and states, but non-negligible for the excitation of the state. Nevertheless, the inclusion of multistep excitation paths is not sufficient to generate a fit to the data with the shell model wave functions. Major modifications are needed in the radial dependence of the neutron and proton parts of the transition density for the → one-step process.
