Fragments kinetic energy distribution and half-life for the true ternary fission of ²⁵⁴ Cf isotope

This study explores the ternary fission of 254 Cf isotope, focusing on various fragmentation in the collinear fragment geometry. The analysis considers the role of magic, double-magic, and even–even fragments in determining the driving potential, the penetration probability, the yield, and the decay constant. The results show that the collinear geometry is energetically favored due to lower driving potential, especially when magic or near-magic fragments are involved. Also, the kinetic energy distribution of the fragments is calculated for under study combinations. Using the momentum and the energy conservation, the fission Q-value is shared among the fragments in various fragmentation. The results indicate that collinear geometries lead to a more balanced energy distribution, when lighter fragments located at the middle position between other two fragments. This agrees well with the observations and provides a clearer picture of the energy dynamics in ternary fission. These findings highlight the influence of the nuclear structure on fragment selection and the energy partitioning, offering new insights into the mechanism for the ternary fission of 254 Cf isotope.
