Abstract

The recoil-tagging technique has been employed to perform an in-beam gamma-ray spectroscopic study of the transfermium nucleus ²⁵⁴No. The experiment was carried out at the Department of Physics of the University of Jyväskylä and utilised the JUROGAM array of germanium detectors coupled to the gas-filled recoil separator RITU. The ground-state rotational band was extended and evidence for non-yrast states was observed for the first time.
