Penetration of realistic potential barrier of H-I fusion

The calculations of heavy-ion fusion cross sections in the above and sub-barrier regions are presented. A barrier penetration model with matrix method for the calculations of transmission coefficients through real one-dimensional barrier of nucleus-nucleus potential is used. The renormalization parameter NS of Satchler-Love M3Y nuclear potential and critical radius Rcr are the two parameters of the model. A very good description of the experimental fusion cross sections for lp-shell colliding ions was obtained for the full measured energy range. It was found that both parameters NS and reduced critical radius rcr are very similar for all systems considered and are-energy independent. 3 figs., 1 tab., 22 refs. (author)
