Fusion-Evaporation Cross Sections in Reactions Leading to Production of Super-Heavy Nuclei

Fusion-evaporation cross sections were calculated for the 48Ca+204-208Pb and 50Ti+206,208Pb reactions and compared with the existing experimental data of the Dubna and GSI groups. The survival probabilities of the compound Z = 102 and Z = 104 nuclei formed in these reactions were calculated using a...

Description
Summary:Fusion-evaporation cross sections were calculated for the 48Ca+204-208Pb and 50Ti+206,208Pb reactions and compared with the existing experimental data of the Dubna and GSI groups. The survival probabilities of the compound Z = 102 and Z = 104 nuclei formed in these reactions were calculated using a Monte Carlo program based on the conventional Bohr-Wheeler theory of fission and statistical model of particle evaporation with Reisdorf-Ignatyuk prescription for the level densities and Strutinsky shell corrections of Moller et al. 'Empirical' magnitudes of the dynamical hindrance of fusion have been deduced for these reactions.
