Theoretical investigation of α-decay in heavy and superheavy isomers

The heavy and superheavy elements of the periodic table predominately disintegrate by [Formula: see text]-decay, facilitating transitions mainly between ground states and occasionally involving isomeric states. This study focuses on estimating the half-lives of [Formula: see text]-transitions both from and to isomeric states, using a recently refined formula which shows excellent agreement with experimental data when isospin of parent nucleus as well as angular momentum taken away by the [Formula: see text] particle is incorporated. These findings provide valuable insights for upcoming experimental investigations of isomeric states. Additionally, the study predicts potential [Formula: see text]-decay in several yet-unobserved isomeric nuclei, contributing to a deeper understanding of nuclear structure in heavy and superheavy elements.
