Derivation of a coupling potential for Coulomb-nuclear interference effects

Abstract

A collective coupling potential for surface vibrations is calculated from an extended liquid drop model. It describes Coulomb and nuclear excitations. Applying the potential to the reaction ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$(${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}\prime$)${}_{}{}^{58}{}_{}{}^{}\mathrm{N}\mathrm{i}*$, we obtain a good agreement with recent experimental data.
