Low lying isomers in the region of superheavy nuclei

Abstract

In the present study we want to give an overview on low lying isomeric states in the heaviest nuclei. After a short report on the early history on the discovery of nuclear isomerism and attempts to understand their physical nature, decay probabilities and structure of all low lying isomeric states in heaviest nuclei with half-lives typically longer than one microsecond are presentet. Special emphasisis is laid on cases where the above mentioned properties are still unclear or under discussion. We do not claim to have solved the problems in that cases, we rather want to give som hints for further discussions.
