Abstract

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 ground state. The results agree with previously known transition energies but disagree with the tentative structural assignments made in earlier work.
