Excitation functions for inelastic scattering of ..pi../sup -/ from /sup 48/Ca to the 1/sup +/ state at 10.2 MeV have been measured at constant momentum transfer q = 73 MeV/c. The incident energy was varied between 116 and 180 MeV. An upper limit was measured for the ..pi../sup +/ cross section at 116 MeV. The data are not fitted by distorted-wave impulse approximation calculations at this q where the differential cross section is predicted to have its maximum. The discrepancy between theory and experiment is similar to the disagreement observed for /sup 12/C(..pi..,..pi..')/sup 12/C(1/sup +/ ,15.1 MeV).
