  Fission properties of the actinide nuclei are deduced from theoretical
analysis. We investigate potential energy surfaces and fission barriers and
predict the fission fragment mass-yields of actinide isotopes. The results are
compared with experimental data where available. The calculations were
performed in the macroscopic-microscopic approximation with the
Lublin-Strasbourg Drop (LSD) for the macroscopic part and the microscopic
energy corrections were evaluated in the Yukawa-folded potential. The Fourier
nuclear shape parametrization is used to describe the nuclear shape, including
the non-axial degree of freedom. The fission fragment mass-yields of considered
nuclei are evaluated within a 3D collective model using the Born-Oppenheimer
approximation.
