Fission barriers and neutron gas in compound superheavy nuclei Original Research Article

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 278112 and 292114. On the other hand, the energy dependence of thermal neutron gas has been found to be almost identical for both systems.
