Theoretical study of evaporation cross sections in the synthesis of very neutron-deficient nuclei

Le résumé fourni par la source

The synthesis of rare-earth neutron-deficient nuclei with large $Z/N$ ratio $\ensuremath{\approx}0.88$ is studied within the framework of the standard statistical model. The fusion cross sections are calculated on the basis of the nuclear reaction video model. The deexcitation process is calculated with the help of the statistical code alice. It is found that the excitation functions can be predicted using a few exited experimental data by carefully choosing the input parameters in the statistical model. The results obtained show that a satisfactory description of the experimental evaporation cross sections requires a great reduction in the theoretical fission barriers.
