Forward-angle pion inelastic scattering was measured for /sup 12/C, /sup 28/Si, and /sup 40/Ca to search for the predicted (but previously unobserved) spin-flip dipole state in these nuclei. Earlier theoretical models suggested that pion inelastic scattering angular distributions would peak at zero degrees for these transitions unlike those for non-spin-flip dipole states. Pion inelastic scattering angular distributions at T/sub ..pi../ = 164 MeV were also measured for the isoscalar, natural-parity states of /sup 16/O and low-lying monopole states in /sup 12/C and /sup 28/Si to test the distorted-wave impulse approximation (DWIA) model of pion inelastic scattering. Existing structure information for these sites enable this quantitative test of the DWIA model. Generally, good agreement was found between these calculations and the data. Large discrepancies were observed, through, for the /sup 16/O(1/sub 1//sup -/, 4/sub 1//sup +/, O/sub 3//sup +/) states and the forward-angle cross sections for the /sup 12/C(O/sub 2//sup +/) state. These discrepancies demonstrate the need for the contribution of higher order processes to pion scattering.
