Influence of shell effects on mass asymmetry in fission of different Hg isotopes

With the improved scission-point model mass distributions are calculated for induced fission of Hg isotopes with even mass numbers A = 174 – 198. The calculated mass distributions and mean total kinetic energy of fission fragments are in good agreement with the existing experimental data. The asymmetric mass distribution of fission fragments of 180Hg observed in the recent experiment is explained. The change in the shape of the mass distribution with increasing A of the fissioning AHg nucleus from symmetric for 174Hg to asymmetric around 180Hg, and to more symmetric for 192−198Hg is revealed.
