Abstract
Angular distributions of 15.0-MeV deuterons scattered by were measured between . Inelastic groups leaving in its five lowest-lying excited states were observed using two position-sensitive detectors placed in the focal plane of a split-pole spectrometer. The elastic-scattering cross section was analyzed using an optical model. values for the transitions from the +(0.197-MeV) and the +(1.56-MeV) states to the ground state were found to be 9±3 and 10±3 W.u. (single-particle units). They were calculated from the deformation parameter extracted from a distorted-wave Born-approximation (DWBA) analysis using a complex form factor derived from the optical-model analysis with a surface-absorption term. These results are in good agreement with results obtained from inelastic proton scattering and from Coulomb-excitation experiments. However, the value for the transition from the 1.35-MeV state was found to be 1.4±0.6 W.u. as compared to the upper limit of 3.8±0.6 W.u. from a () experiment, and to 12.0±4.0 and 7.6±1.3 W.u. from two different Coulomb-excitation experiments. The results are compared to various model predictions.
