Elastic Scattering of Low-Energy Deuterons fromNi60andCd114and the Effect of the Deuteron Electric Polarizability in the Optical-Model Potential

Abstract

Differential cross sections for elastic scattering of deuterons from ${}_{}{}^{60}{}_{}{}^{}\mathrm{Ni}$ and ${}_{}{}^{114}{}_{}{}^{}\mathrm{Cd}$ were measured for deuteron bombarding energies between 5 and 15 MeV. The data were analyzed by means of an optical model that includes a potential due to the deuteron electric polarizability. We conclude that the effects of the polarizability are small, although not negligible, and that nuclear interactions still dominate the elastic scattering at these energies.
