Differential cross sections were measured for pion inelastic scattering from /sup 44/Ca at T/sub ..pi../ = 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 ..pi../sup -/ and ..pi../sup +/ scattering to the low-lying collective states are nearly equal. Neutron and proton matrix elements have been extracted from simultaneous fits to ..pi../sup -/ and ..pi../sup +/ data. The resulting values are in good agreement with data from hadronic and electromagnetic probes.
