Description
An exact finite-range coupled-channel Born-approximation analysis of the 74Ge(18O,16O)76Ge and 76Ge(16O,18O)74Ge reactions has been performed. It shows that the shape change between the angular distributions of different final states is well reproduced by using BCS--random-phase-approximation wave functions to describe the Ge states. The measured transfer cross sections are rather well described by calculations using optical model parameters and deformation values which fit the experimental data on 18O and 16O elastic and inelastic scattering. it has been found that the excitation of the 18O* 2+ state has to be included in the coupled-channel Born-approximation analysis in order to reproduce the experimental angular distributions of the 74Ge and 76Ge ground states. A unique factor of 2.3 can be used to normalize the calculated cross section to the experimental data
