Phys. Rev. C 55, 2541–2555 (1997)Quasielastic transfer in the 136Xe+64Ni reactionReceived 15 October 1996; published in the issue dated May 1997 Single and multinucleon transfer yields for the 136Xe+64Ni reaction at a scattering energy ≈5% above the Coulomb barrier energy are studied using particle–γ-ray coincidence data. Q-value and scattering-angle distributions are extracted for the stronger channels. A fast transfer mechanism dominates the yields to these channels over an extended Q-value range, leading to a concentration of the cross section near the grazing angle. Analysis of the angular distributions based on a semiclassical barrier penetration model suggests that the single-nucleon and two-neutron exchange channels are dominated, respectively, by direct and two-step sequential transfer from the ground or low-lying excited states of the participating nuclei. The multiproton transfer channels have angular distributions that indicate a more complex mechanism, although direct cluster transfer from an excited configuration cannot be fully discounted. In a separate analysis, the relative population of different mass channels is found to be in general agreement with the expectations of a “random walk” model of particle exchange. © 1997 The American Physical Society URL:
