[en] At low excitation energies fission mechanism is strongly influenced by the nuclear structure of the fissioning nucleus. The shell stabilization in the fragments results in either asymmetric mass-division or symmetric mass-division. As part of the systematic study of mass distribution of the neutron deficient Thorium nuclei, presented are the results on the fission fragment mass distribution (FFMD) for ²²²Th nucleus measured at moderate excitation energies. The ²²²Th compound nucleus (CN) is populated through the fusion reaction of ¹⁸O+²⁰⁴Pb
