چکیده
The fusion evaporation-residue cross sections for 32 S+ 184 W have been mea-246, and 257 MeV using the ATLAS Fragment Mass Analyzer. The data are compared with Statistical Model calculations and it is found that a nuclear dissipation strength, which increases with the excitation energy is required to reproduce the excitation function. A comparison with previously published data shows that the dissipation strength depends strongly on the shell structure of the nuclear system.

Phase transitions of small isolated systems are signaled by the shape of the caloric equation of state e∗(T ), the relationship between the excitation energy per nucleon e∗ and temperature. In this work we compare the experimentally deduced e∗(T ) to the theoretical predictions. The experimentally accessible temperature was extracted from evaporation spectra from incomplete fusion reactions lea...
