Abstract
True ternary fission of heavy nuclei has been predicted under conditions of large \(Z^2/A\)-parameters, and a decay into three fragments of comparable masses has been predicted repeatedly. Studies for these ternary decays with third fragments with masses around \(A=40\) have been done using the missing mass approach with two FOBOS-detectors in coincidence at 180\(^\circ \). A new kind of radioactive fission decay, the so called collinear cluster tri-partition (CCT) has been discovered as reported in Refs. [1, 2], namely for spontaneous fission of \(^{252}\)Cf(sf) and with neutron induced fission in \(^{235}\)U(n, fff). We discuss the dynamics of the collinear ternary fission decay in a model, where the ternary decay is considered to be a sequential process of two binary decays, with two neck ruptures in a strongly deformed (hyperdeformed) nucleus. The kinetic energy of the third fragments are calculated as well as the potential energy surfaces are discussed for the ternary collinear decay.
