Theoretical Investigation of α-decay in Heavy and Superheavy Isomers

The heavy and superheavy elements of the periodic table predominately disintegrate by α-decay, facilitating transitions mainly between ground states and occasionally involving isomeric states. This study focuses on estimating the half-lives of α-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 α particle are incorporated. These findings provide valuable insights for upcoming experimental investigations of isomeric states. Additionally, the study predicts potential α-decay in several yet-unobserved isomeric nuclei, contributing to a deeper understanding of nuclear structure in heavy and superheavy elements.
