Mass and charge dispersion of ²²4^,230Th nuclei using Skyrme Energy Density Formalism within the collective clusterisation approach

In the recent experimental study of nuclear fission of the Thorium isotopic chain, a transition of symmetric to asymmetric fission has been observed, as one moves from ²²²Th to ²³⁰Th nuclei. For lighter-mass isotopes of Thorium, i.e. ^222,224Th, it has been observed (at E*_CN >11 MeV) that, the asymmetric fission mode starts appearing with a small effect, in comparison to the symmetric fission. In view of above observation, the present work is aimed to explore the symmetric and asymmetric fission modes via the mass and charge distributions of ^224,230Th nuclei, at E*_CN ≈ 20 MeV. For above analysis, the preformation probability (P₀) and fragmentation potential (V (ƞ)) have been calculated within the framework of Dynamical Cluster-decay Model (DCM), based on the Quantum Mechanical Fragmentation Theory (QMFT)
