The fission yields of mercury isotopes were calculated and evaluated by using the improved scission point model. The asymmetric fission of 180Hg was analyzed within the framework of the scission point model with octupole deformed fragments. The fission mass asymmetry of 180Hg is attributed to the influence of N = 44, 56 and Z = 34, 46 shell gaps for octupole deformations and the liquid drop model. The evolution of proton and neutron numbers in asymmetric fragments of mercury isotopes is also explained by octupole deformed shell gaps.
