Search for possible way of producing super-heavy elements-Dynamic study on damped reactions of 244Pu+244Pu,238$U+238$U and 197Au+197Au

Abstract

By using the improved Quantum Molecular Dynamics model, the ${}^{244}$Pu+${}^{244}$Pu, ${}^{238}$U+${}^{238}$U and ${}^{197}$Au+${}^{197}$Au reactions at the energy range of $E_{c.m.}$=800 $MeV$ to 2000 $MeV$ are studied. We find that the production probability of superheavy fragments(SHF) with $Z\ge$ 114 is much higher for ${}^{244}$Pu+${}^{244}$Pu reaction compared with that of ${}^{238}$U+${}^{238}$U reaction and no product of SHF is found for ${}^{197}$Au+${}^{197}$Au. The production probability of SHF is narrowly peaked in incident energy dependence. The decay mechanism of the composite system of projectile and target and the time scale of decay process are explored. The binding energies of superheavy fragments are found to be broadly distributed and their shapes turn out to be exotic form.
