Abstract: (APS)
Analyzing-power angular distributions have been measured for prominent states excited by the Mg24(p→,d) reaction at 94.8-MeV bombarding energy. The distributions for the known low-lying hole states (Ex<6 MeV) exhibit a clear j dependence with characteristic features which are most pronounced near 6° for l=1 transitions, and near 35° for l=2 transitions. The analyzing powers observed for l=0 pickup are strongly oscillatory, reaching a value ≅0.9 near 20°. These measured spin signatures allow the identification of "deephole" p states at 8.91-, 9.67-, and 10.57-MeV excitation in Mg23 as p32−1 and of a state at 9.02 MeV as p12−1. Difficulties in reproducing the behavior of the measured cross sections and analyzing powers using standard distorted-wave Born approximation calculations are apparent, particularly for l=0 transitions.
