Kr86(d, p)Kr87Reaction

Abstract

States of ${}_{}{}^{87}{}_{}{}^{}\mathrm{Kr}$ have been investigated via the ${}_{}{}^{86}{}_{}{}^{}\mathrm{Kr}(d, p){}_{}{}^{87}{}_{}{}^{}\mathrm{Kr}$ reaction, with 11-MeV deuterons and an over-all energy resolution of 30 keV. Proton groups leading to 23 states in ${}_{}{}^{87}{}_{}{}^{}\mathrm{Kr}$ have been identified. The angular-distribution data have been analyzed using finite-range distorted-wave Born-approximation (DWBA) calculations to extract spectroscopic information. Spin and parity assignments, excitation energies, and spectroscopic factors for most of the observed levels are presented. Comparisons are made with preliminary data of proton elastic scattering from ${}_{}{}^{86}{}_{}{}^{}\mathrm{Kr}$ at isobaric analog resonances.
