Fission fragment mass yields of Th to Rf even-even nuclei *

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