Abstract
The cross sections of the formation of Ac-, Ra- and Fr-evaporation res idues in the Ne-20 + Au-197 reaction have been measured by means of th e VASSILISSA kinematic separator in the range of the compound-nuclei e xcitation energies from 40 to 120 MeV. The experimental data have been analyzed on the basis of the statistical model of excited nuclei deca y. The influence of different assumptions about the parameters of fiss ion barriers on calculation results was considered.
