Abstract

Differential cross sections and analyzing powers are presented for discrete states of C12 up to 21-MeV excitation energy as observed by the C12(p', p2)C12 reaction at 200 MeV. The results of distorted-wave, impulse-approximation calculations with a 210-MeV free nucleon-nucleon t matrix are compared with the data for most of the transitions. The comparisons are divided into classes that emphasize different aspects of the effective interaction. As a whole, the comparisons are comparable to those at lower energies. However, the description of the 15.11-MeV transition to a 1+, T=1 state is decidedly inferior. The effects of removing abnormal-parity amplitudes with S=1 are considered for several transitions. In particular, their removal produces good agreement for the 15.11-MeV state. NUCLEAR REACTIONS C12(p', p2)C12, E=200 MeV, measured (Ep,), Ay(Ep,); =6°-60°, Ex=0-21 MeV. DWIA analysis.
