$$gamma$$-rays decay study of two K isomers in $$^{254}$$No was performed. Two new transitions of 778 and 856 keV could be attributed to the decay pattern of $$^{254m1}$$No (T$$_{1/2}$$=275 ms). The population of an excited band built up on this isomer ($$K$$$$^{pi}$$=8$$^{-}$$) by the decay of $$^{252m2}$$No (198 $$mu$$s) could be proven. A spontaneous fission branch of 2.0$$times$$10$$^{-4}$$ was measured for $$^{252m1}$$No, and upper limit of 1.2$$times$$10$$^{-4}$$ was estimated for $$^{252m2}$$No. These values demonstrate the high stability of multi-quasiparticle configuration against spontaneous fission.
