- Abstract
While it is well established that the ground state reorientation coupling can have a significant influence on the elastic scattering of deformed nuclei, the effect of such couplings on transfer channels has been much less well investigated. In this letter we demonstrate that the 208 Pb (7 Li , 6 He) 209 Bi proton stripping reaction at an incident energy of 52 MeV can be well described by the inclusion of the 7 Li ground state reorientation coupling within the coupled channels Born approximation formalism. Full finite-range distorted wave Born approximation calculations were previously found to be unable to describe these data. Addition of coupling to the 0.478-MeV 1 / 2 - excited state of 7 Li , together with the associated two-step transfer path, has little or no influence on the shape of the angular distributions (except that for stripping leading to the 1.61-MeV 13 / 2 + level of 209 Bi which is significantly improved) but does affect appreciably the values of the 209 Bi → 208 Pb + p spectroscopic factors. Implications for experiments with weakly-bound light radioactive beams are discussed.
