Fission analysis of Z  = 114 superheavy isotopes formed via heavy-ion induced reactions

AbstractThe quasi-fission and fission mass distributions for48Ti  + 238U  → 286Fl* and48Ca  + 244Pu  → 292Fl* reactions are investigated within dynamical cluster decay model by addressing the experimentally available symmetric fission (A/2  ± 20) and asymmetric quasi-fission cross-sections in nuclear deformation space. The contribution of quasi-fission components comes out to be negligibly small for spherical constitution of fragments, which increases significantly on adding deformation effects with the appearance of some sharp p eaks in the neighborhood of Z = 82 magicity. The contribution of quasi-fission events increases with increase in isotopic mass of superheavy system with Z = 114.
