Description

We have detected the electrons accompanying the decay of a long-lived isomer in 254No, which was produced with the 208Pb(48Ca,2n) reaction. Time and spatial correlations of A = 254 evaporation residues, isomeric electrons and ground-state α-particles confirmed the existence of the isomer. The measured electron sum-energy spectrum favors a Kπ = 7- assignment for the isomer
