Structure of rotational bands in 253No

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 \(\ensuremath 9/2^-[734]_{\nu}\) ground state. The results agree with previously known transition energies but disagree with the tentative structural assignments made in earlier work.
