“…Sun [27] contributes a theoretical perspective to the study of K−isomers, particularly employing the angular-momentum-projected shell model, which is efficient in truncating the usual shell model space for heavy and deformed nuclei. Xu et al [28] provide a theoretical review focused on the collective rotation of high-K isomers leveraging the configuration-constrained total Routhian surface calculations based on a macroscopic-microscopic model. Despite long and successful theoretical efforts on K isomers, the decay properties of K isomers are still an open issue necessitating future efforts.…”
