Abstract

A detailed \( \gamma\) spectroscopic decay study of two K isomers in 254No was performed. In addition to the previously reported \( \gamma\) lines two new transitions of E = 778 , 856keV could be attributed to the decay pattern of 254m1No ( T 1/2 = 275±7 ms). The population of an excited band built up on this isomer ( \(\ensuremath K^{\pi} =8^{-}\) by the decay of 254m2No ( T 1/2 = 198±13 μs) could be proven by measuring delayed \( \gamma\) -\( \gamma\) coincidences between transitions stemming from the decay of both isomeric states. The energies of the band members could be established up to \(\ensuremath I^{\pi} = 15^{-}\) . A spontaneous fission branch of (2.0±1.2)×10-4 was measured for 254m1No , an upper limit of \( \le\)1.2×10-4 was estimated for 254m2No . These values demonstrate the high stability of multi-quasiparticle configurations against spontaneous fission. Evidence for an \( \alpha\) decay branch of 254m1No in the order of 1×10-4 was found.
