Abstract

We carried out exact finite-range coupled reaction channel analysis for oneand two-proton stripping channels in the collision ¹¹⁶Sn+⁶⁰Ni, based on a parameter free double-folding potential. Large-scale shell model calculations were performed for obtaining spectroscopic amplitudes for projectile and target overlaps. Transition between the ground states was found to contribute the maximum to the one-proton stripping cross sections. Data for two-proton stripping were significantly underpredicted by the successive and the microscopic cluster transfer mechanisms. The extreme cluster model for the transfer of a pair of nucleons was successful in reproducing the data for two-proton stripping channel. No arbitrary scaling of the cross sections had to be invoked in our analysis. Information on individual transitions, inclusion of additional states in the intermediate partition and more realistic shell model calculations may further refine our results.
