Abstract

Using formulae for calculating the widths of spontaneous and thermal neutron-induced ternary fission of atomic nuclei with the light charged particles emission, based on the approach to ternary fission as a virtual process, as well as experimental energy distributions of α-particles, hydrogen isotopes and 6He nuclei in ternary fission of actinide nuclei, the probabilities of the third particles formation in the neck of the fissile nucleus, which turn out to be close to each other for (s, f) and (nth, f) fission reactions of the corresponding nuclei, were estimated. It was shown, that the spontaneous and induced ternary fission of the actinide nuclei under consideration with the emission of light charged particles and nucleons comes from close configurations of the fissile nucleus, and the thermal neutron binding energy introduced into the compound fissile nucleus in reactions (nth, f) goes into the deformation energy of the fissile nucleus, and not into the kinetic energy of the third particle.
