Structure of rotational bands in ~(253)No

摘要

In-beam gamma-ray and conversion electron spectroscopic studies have been performed on the ~(253)No nucleus. A strongly coupled rotational band has been identified and the improved statistics allows an assignment of the band structure as built on the 9/2[734]ν ground state. The results agree with previously known transition energies but disagree with the tentative structural assignments made in earlier work.
