/sup 24/Mg(p,d) analyzing-power measurements at 95 MeV

1982 
Analyzing-power angular distributions have been measured for prominent states excited by the /sup 24/Mg(p,d) reaction at 94.8-MeV bombarding energy. The distributions for the known low-lying hole states (E/sub x/<6 MeV) exhibit a clear j dependence with characteristic features which are most pronounced near 6/sup 0/ for l = 1 transitions, and near 35/sup 0/ for l = 2 transitions. The analyzing powers observed for l = 0 pickup are strongly oscillatory, reaching a value approx. =0.9 near 20/sup 0/. These measured spin signatures allow the identification of ''deep-hole'' p states at 8.91-, 9.67-, and 10.57-MeV excitation in /sup 23/Mg as p/sub 3/2/ /sup -1/, and of a state at 9.02 MeV as p/sub 1/2/ /sup -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.
