Inelastic scattering and one-neutron-transfer reactions of O18+Ca40

Inelastic scattering of O18+Ca40 was investigated at Ec.m.=42.85 MeV in order to study the influence of coupled channels effects. Angular distributions were measured in the angular range θlab=5°-45°for elastic scattering and inelastic excitation of the 3-(3.737 MeV), 2+(3.905 MeV), 5-(4.492 MeV) states in Ca40 and the 2+(1.982 MeV) and 3-(5.098 MeV) states in O18. The results are compared to distorted-wave Born approximation and coupled channel calculations employing collective form factors. The improvements of the coupled channel predictions over those of the distorted-wave Born approximation are less dramatic than observed previously for O16+Ca40. With the exception of the ground state transition, the spectroscopic factors for the one-neutron-transfer reaction Ca40(O18, O17)Ca41 are in good agreement with those observed in light ion induced reactions.
