VIRTUAL CHARACTER OF THE EMISSION OF THE THIRD LIGHT PRESCISSION NUCLEI IN THE TERNARY SPONTANEOUS AND INDUCED FISSION OF HEAVY NUCLEI

Within the framework of the quantum fission theory on the base of the mechanism of the intermediate nucleus formation in the virtual state, research continues on the experimental characteristics of prescission light nuclei for cases of ternary spontaneous and induced fission (with the participation of thermal neutrons) of heavy nuclei 252Cf and 235U, 239Pu, respectively. On the basis of Gamow's alpha-decay theory, the probabilities of the formation of ω_(n_3 ) nuclei in the parent nuclei were calculated. It was found that for the cases of the appearance of third particles in two types of fission (spontaneous and induced), such characteristics as the values of the yields δ_(n_3 ), the maxima of the experimental energy distributions T_(n_3 max), as well as the probabilities of formation of ω_(n_3 )obtained in this work for prescission light nuclei, are close.
