The Coulomb barrier parameters have been calculated for a spherical-deformed interacting pair of nuclei using fourteen different versions of the proximity approaches and a simple analytical formula for the Coulomb part of the heavy ion potential. The results of these proximity versions have been compared with more accurate results obtained from the double folding model (DFM). We have considered the interacting pair 48 Ca + 238 Pu as an example and assumed the presence of the quadrupole, octupole and hexadecapole deformation parameters for 238 Pu. The orientation angle dependence of the Coulomb barrier parameters has been computed for different sets of the deformation parameters. We found that the proximity types named; Prox77, BW Prox91, AW Prox95, Bass Prox77 and Bass Prox80 are the best ones of the available fourteen versions of the proximity approaches for calculating the nuclear part of the interaction potential for a spherical-deformed pair of nuclei.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
