Abstract
The structure of high-spin and nonyrast states of the transfermium nucleus has been studied in detail. The isomeric nature of a two-quasiparticle excitation has been exploited in order to obtain spectroscopic data of exceptional quality. The data allow the configuration of an isomer first discovered over 30 years ago to be deduced, and provide an unambiguous determination of the location of neutron single-particle states in a very heavy nucleus. A comparison to the known two-quasiparticle structure of confirms the existence of the deformed shell gaps at and .

Weighty matters
Published 18 August 2008
The long-held belief that nuclear states of very heavy elements that carry a large angular momentum would be unstable has been shattered in recent years. Now, a new experiment that can probe the outermost nuclear orbitals in studies these states and poses a challenge to theory.
