摘要
Fission and neutron emission are the principal cooling mechanisms of the compound superheavy nuclei. In the framework of the Finite-Temperature Hartree-Fock-Bogoliubov method, the fission barriers and neutron gas have been studied in the excited superheavy systems. Very different energy dependence of fission barriers has been found for (278)112 and (292)114. On the other hand, the energy dependence of thermal neutron gas has been found to be almost identical for both systems.
