Systematics of ( p → ,   d ) analyzing powers at 94 MeV

Analyzing-power angular distributions of the (p,d) reaction on /sup 60/Ni, /sup 86/Sr, and /sup 208/Pb have been measured at 94-MeV bombarding energy. A distinctive j dependence was observed for the pickup of neutrons from the p/sub 1/2/, p/sub 3/2/, f/sub 5/2/, and f/sub 7/2/ orbitals which is independent of target mass and of the number of nodes in the neutron bound-state radial wave function. These characteristic j = l +- (1/2) signatures may thus be used as experimental templates for reliable spin determinations over the whole periodic table at this bombarding energy. Conventional distorted-wave Born approximation calculations using standard optical model parameters describe the experimental analyzing power angular distributions and the associated j dependence rather poorly.
