Differential cross sections were measured for 50 MeV + and - elastic scattering from C12 and for 50 MeV + inelastic scattering to the (4.44 MeV, 2+), (7.65 MeV, 02+), (9.64 MeV, 3-), (12.71 MeV, 1+), and (15.11 MeV, 1+) levels in C12. Comparisons of the data obtained in this study to data taken previously for these states resolve discrepancies between the earlier data sets. Using a recently discussed procedure, one-step and coupled-channels calculations using a modified MSU potential were performed. The results of both one-step and coupled-channels calculations describe the data for the ground, first, and third excited states, indicative of the collective isoscalar structure of those states. The one-step analysis fails to describe the excitation of the 02+ state. The coupled-channels calculations are more successful in describing those data, indicating that the failure of the one-step calculations may be attributed to coupled-channels effects.
