Abstract: (APS)
The proton polarization from the Ca40(d,p)Ca41 ground-state (g.s.) reaction has been measured in the angular range from 15° to 90° at a mean deuteron energy of 14.3 MeV. The Ca40(d,d)Ca40 and the Ca40(d,p)Ca41 g.s. differential cross sections were determined at the same bombarding energy and within the same angular range. A preliminary analysis of the data in terms of the distorted-wave Born approximamation theory is presented. Most calculations were performed in the zero-range approximation with local optical potentials, but including the effects of nonlocality in the approximation of Perey. The inclusion of finite range improved the fit to the (d,p) cross sections but had little effect on the polarization. Although a good fit to the polarization data has not been obtained, it is clear that a spin-orbit term is needed in the deuteron optical potential, and furthermore, the indications are that the imaginary part of the spin-orbit potential has to be positive or zero.References(21)
