Abstract

A Kramers-modified statistical model is used to calculate the cross-section of the evaporation residue, fission cross-section, average pre-fission multiplicities of protons and α-particles for 216Ra formed in 19F+ 197Au reactions and results are compared with the experimental data. To calculate these quantities, the effects of temperature and spin K about the symmetry axis have been considered in the calculations of the potential energy surfaces and the fission widths. It is shown that the results of the calculations using values of the temperature coefficient of the effective potential k = 0.008±0.003 MeV − 2 and scaling factor of the fission-barrier height r s = 1.004±0.002 are in good agreement with the experimental data.
