Differential cross sections were measured for pion inelastic scattering from 44Ca at T=180 MeV. The low-lying collective states were analyzed using distorted-wave impulse-approximation calculations with transition densities obtained from electron and previous pion scattering. The cross sections for π- and π+ scattering to the low-lying collective states are nearly equal. Neutron and proton matrix elements have been extracted from simultaneous fits to π- and π+ data. The resulting values are in good agreement with data from hadronic and electromagnetic probes.
