“…Here we show that the 52-MeV 208 Pb( 7 Li, 6 He) 209 Bi single-proton stripping data of Zeller et al [4], which the FR-DWBA also failed to describe satisfactorily, may be fitted simply by including the ground state reorientation coupling of the 7 Li projectile, provided the description of the entrance channel elastic scattering data is maintained when the coupling is included. While the influence of ground state 0123456789().…”

“…Inputs to the CCBA calculations were kept as similar as possible to those of the original FR-DWBA calculations of Ref. [4], with the exception that the spectroscopic amplitudes for the 7 Li| 6 He+ p overlaps were taken from [8] rather than Cohen and Kurath [9] in order to have a consistent set for all the overlaps required. However, the spectroscopic amplitudes of Refs.…”

Important Influence of Entrance Channel Reorientation Coupling on Proton Stripping

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 $$^{208}\hbox {Pb}(^7\hbox {Li},^6\hbox {He})^{209}\hbox {Bi}$$ 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 $$^7\hbox {Li}$$ 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 $$1/2^-$$ 1 / 2 - excited state of $$^7\hbox {Li}$$ 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 $$13/2^+$$ 13 / 2 + level of $$^{209}\hbox {Bi}$$ 209 Bi which is significantly improved) but does affect appreciably the values of the $$^{209}\mathrm {Bi} \rightarrow {^{208}\mathrm {Pb}} + p$$ 209 Bi → 208 Pb + p spectroscopic factors. Implications for experiments with weakly-bound light radioactive beams are discussed.
