A numerical method is used to obtain the optimum cold fission paths fo
r three decay modes of U-234. The WKB-integral is minimized with respe
ct the necking and the elongation. A term which takes into account the
effect of the diffuse surface is added to the deformation energy in t
he framework of the macroscopic model of binary system with different
charge densities. The effective masses are computed with more correct
coordinates of deformation in order to include the variations of the a
symmetry during the processes. Calculations are performed to obtain th
e fission trajectories in a large range of mass-asymmetry including co
ld fission, cluster emission and alpha-decay. Estimations of T-1/2 are
reported.
