Inelastic scattering ofLi6fromNi58at 71 MeV

Nine excited states of ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$ were studied via the ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$(${}_{}{}^6{}_{}{}^{}\mathrm{Li}$,${}_{}{}^6{}_{}{}^{}\mathrm{Li}$) reaction at 71.2 MeV. Two methods were employed to analyze the data. They were the distorted wave Born approximation, and the method of coupled channels. A comparison of their predictions and the information they provide about the nuclear deformation lengths is presented. In agreement with the Austern-Blair model for strongly absorbed particles, all five parameter sets produced equally good fits to the inelastic data.
