“…The pairing energy of the fragment, ∆ i , and its shell correction, δW i , are tabulated in Ref. [30] based on the mass formula of Koura et al [32]. If δW i is negligible or if U is large then the renormalization of a i is immaterial and the BSFG level-density parameter reverts to the simple form, a i ≈ A i /e 0 [64].…”

A new dynamical cascade code for decaying hot nuclei is proposed and specially adapted to the synthesis of super-heavy nuclei. For such a case, the interesting channel is the tiny fraction that will decay through particles emission, thus the code avoids classical Monte-Carlo methods and proposes a new numerical scheme. The time dependence is explicitely taken into account in order to cope with the fact that fission decay rate might not be constant. The code allows to evaluate both statistical and dynamical observables. Results are successfully compared to experimental data.

“…The pairing energy of the fragment, i , and its shell correction, δW i , are tabulated in Ref. [8] based on the mass formula of Koura et al [9]. The overall scale e 0 is taken as a model parameter but it should be noted that if the shell corrections are negligible, δW i ≈ 0, or the available energy, U i , is large, then a i ≈A i /e 0 , i.e.…”

Abstract. For many years, the state of the art for modeling fission in radiation transport codes has involved sampling from average distributions. However, in a true fission event, the energies, momenta and multiplicities of emitted particles are correlated. The FREYA (Fission Reaction Event Yield Algorithm) code generates complete fission events. Event-by-event techniques such as those of FREYA are particularly useful because it is possible to obtain complete kinematic information on the prompt neutrons and photons emitted during the fission process. It is therefore possible to extract any desired correlation observables. We describe FREYA and compare our results with neutron-neutron, neutron-light fragment and neutron-photon correlation data.
