We employ a theoretical framework motivated by a microscopic phenomenological approach involving Skyrme force model to account for the interaction of [Formula: see text]-particle with the nucleons of [Formula: see text]-radioactive nucleus. The realistic calculations for [Formula: see text]-particle preformation probabilities ([Formula: see text]) of even–even nuclei whose atomic numbers lie in the range [Formula: see text] are performed. Through the calculations of assault frequency possessed by [Formula: see text]-particle, shell effects are naturally incorporated in this methodology. The obtained results are then subjected to fitting procedures, resulting in a comprehensive fit within [Formula: see text]-scheme. These fitted [Formula: see text]-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 [Formula: see text]-decay and spontaneous fission (SF). Twelve [Formula: see text]-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.
