Study of theZr90(d, p)Zr91Reaction

Measurements have been made of the differential cross section and polarization of protons from the ground state ($l_n=2\mathrm{}$) and the 1.2-MeV state ($l_n=0\mathrm{}$) in the ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}(d, p){}_{}{}^{91}{}_{}{}^{}\mathrm{Zr}$ reaction using 11-MeV deuterons. Measurements were also made of the elastic scattering cross section for 11-MeV deuterons and of the elastic scattering cross section and polarization for 14.8- and 16.0-MeV protons. An optical-model analysis was made of the elastic scattering results, and the potentials obtained were used in a distorted-wave Born approximation (DWBA) analysis of the ($d, p$) experiment. Except at forward angles, the DWBA calculation does not follow the trend of the polarization data for the protons from the 1.2-MeV state, where only the spin-orbit interactions contribute to the polarization. The polarization of the protons from the ground state was small at forward angles and could not be described by the DWBA analysis using the same geometrical parameters for the deuteron spin-orbit and real-central potentials.
