Abstrakt: Results obtained by measuring the energy dependence of the probability of 232Th ternary fission in the region of vibrational resonances are presented. The measurements were performed by using a double ionization chamber with Frisch grids and a CsI(Tl) scintillation detector. The use of digital methods for pulse processing made it possible to obtain highly reliable results. The data analysis reveals that our value of the ternary-fission probability is compatible with existing systematics, which nevertheless need some correction. The results of our measurements unambiguously indicate that local variations in the total kinetic energy of fission fragments in the region of the individual vibrational resonances cannot be explained by corresponding variations in the ternary-fission probability.© 2004 MAIK “Nauka / Interperiodica”.
