Abstract

The alpha ternary fission half-lives of thorium isotopes have been studied using the Coulomb and proximity potential models. The role of the deformation effects and the angle of orientation were included during the evaluation of the total potential. Fragment combinations were identified using cold valley plots of the driving potential. The half-lives and yields were evaluated using the penetration probability. The dependence of the logarithmic half-lives on different angles of orientation was studied. The evaluated alpha ternary fission yield was compared with that of the available experiments with and without deformations. The half-lives obtained in the present work were compared with those of the available data. Possible alpha ternary fission fragments were identified in the isotopes of thorium. The alpha ternary fission half-lives were compared to the binary fission half-lives. The binary fission half-lives are dominant in the \({^{209-225}}\)Th nuclei, and the ternary fission half-lives are dominant in the isotopes of the \({^{226-238}}\)Th nuclei.
