Suppression of genuine ternary fission in heavy and superheavy nuclei: A self-consistent perspective
In this seminar, I will explore the phenomenon of genuine ternary fission, the spontaneous breakup of a nucleus into three medium-mass fragments, using fully self-consistent Hartree–Fock–BCS calculations with the SLy6 Skyrme interaction. Building on our earlier work in the actinide region, we extend the investigation to superheavy nuclei, where stronger Coulomb repulsion, extreme deformations, and elongated shapes may (or may not) offer new pathways to ternary breakup.
A central focus will be the construction of self-consistent energy landscapes for two distinct ternary geometries: collinear tripartition, in which fragments align along a single axis, and equatorial tripartition, where fragments emerge in a triangular arrangement. A simplified Langevin-based framework is used to estimate the dynamical competition between ternary and the overwhelmingly dominant binary fission. By combining these approaches for both heavy and superheavy systems, the seminar will address the broader question: to what extent can genuine ternary fission survive the strong dynamical suppression acting along its fission path?
