Abstract

The angular distributions of the differential cross sections and analyzing powers are presented for the C12(p,π+)C*13 reaction leading to the ground state of C13 as well as some of the C*13 low-lying excited states. The analyzing powers for some of the transitions exhibit a considerable energy dependence while for other transitions they remain relatively unchanged, thus indicating a dynamic sensitivity of the analyzing power dependent on nuclear structure. Comparisons of theoretical predictions for AN0 and dσdΩ, based on microscopic two-nucleon models, with our results indicate that substantial differences between theory and experiment still exist for A(p,π+)A+1 type of reactions.
