Discrimination Between Fission And Quasi-Fission From Reaction Time Measurements

The formation of compound nuclei with Z = 120 and Z = 124 has been evidenced from their very long fission times measured by the blocking technique in single crystals. A possible explanation for the long measured fission times might be found in the temperature dependence of the fission barriers, as predicted by Hartree-Fock-Bogolubov calculations at finite temperature in this super-heavy nucleus domain.
