α-particle clusterization: A reflection of shell closures.

We employ a theoretical framework motivated by a microscopic phenomenological approach involving Skyrme force model to account for the interaction of α -particle with the nucleons of α -radioactive nucleus. The realistic calculations for α -particle preformation probabilities ( P α ) of even–even nuclei whose atomic numbers lie in the range 8 4 ≤ Z ≤ 1 1 8 are performed. Through the calculations of assault frequency possessed by α -particle, shell effects are naturally incorporated in this methodology. The obtained results are then subjected to fitting procedures, resulting in a comprehensive fit within N p N n I -scheme. These fitted α -particle preformation probabilities are utilized to predict the half-lives of unknown superheavy nuclei (SHN). This work not only refines our understanding about radioactive properties of these nuclei but also provides valuable insights into their stability against α -decay and spontaneous fission (SF). Twelve α -decay chains originating from unknown SHN have been identified in this work. The outcomes of this research would contribute to the advancement of predictive models to study the fundamental properties of SHN, offering an experimental verification as well. [ABSTRACT FROM AUTHOR]
