Excited states in 256Rf were populated via the 208Pb(50Ti,2n) fusion–evaporation reaction. Delayed γ-ray and electron decay spectroscopy was performed and three isomeric states in 256Rf have been identiﬁed. A fourth low-energy nonyrast state was identiﬁed from the γ-ray decay of one of the higher lying isomers. The states are interpreted as multi-quasiparticle excitations.
