摘要：

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