An effective Fourier nuclear shape parametrization, which describes well the most relevant degrees of freedom on the way to fission is used to construct a three-dimensional collective model. The potential energy surface is evaluated within the macroscopic-microscopic approach based on the Lublin-Strasbourg drop macroscopic energy and Yukawa-folded single-particle potential. A phenomenological inertia parameter is used to describe the kinetic properties of the fissioning system. The fission fragment mass yields are obtained by using an approximate solution of the underlying Hamiltonian. The predicted mass fragmentations for even-even Pt to Ra isotopes are compared with available experimental data. Their main characteristics are well reproduced when the neck rupture probability dependent on the neck radius is introduced.
