Abstract Evidence for the decay of nonyrast states in 254 No has been observed for the first time, in an experiment performed at the University of Jyvaskyla. The experiment employed the powerful jurogam array of germanium detectors coupled to the gas filled recoil separator ritu and the focal plane spectrometer great. The groundstate rotational band has been tentatively extended up to a spin of 24 hbar and has a smoothly behaving dynamical moment of inertia. It is speculated that the observation of high energy gamma rays is due to the decay of a K = 3 bandhead state. |
