Mechanisms of binary and ternary low-energy fission with taking into account the nonsphericity effect

On the basis of the quantum-mechanical fission theory the wave functions of binary fission fragments and amplitudes of partial fission widths have been built taking into account the strong nonsphericity of fragments' interaction. It has been shown that the strong coupling approximation has been led to the mechanism of orientation of the fragments' symmetry axes in direction of the fissioning nucleus symmetry axis. The mechanism of orientation of spins and relative orbital moments of fission fragments, explaining the appearance of big values of fragments spins in experiments, have been substantiated. These mechanisms have been generalized to the case of ternary fission
