High-spin states have been studied in the very neutron deficient [ital N]=74 nucleus, [sup 136]Sm with the reaction [sup 107]Ag([sup 32]S,[ital p]2[ital n])[sup 136]Sm. Using time-correlated charged-particle--[gamma]--[gamma] spectroscopy, a rotational cascade built upon the [ital t][sub 1/2]=15 [mu]s, [ital K][sup [pi]]=8[sup [minus]] isomer has been identified. Although equivalent isomers are known in other [ital N]=74 isotones, this represents the only case where the associated band has been observed. The in-band decay properties of this structure are consistent with a 7/2[sup +][404][direct product]9/2[sup [minus]][514] two quasineutron assignment. A second high-[ital K] band, probably of a four-quasiparticle nature, is observed to feed into the [ital K][sup [pi]]=8[sup [minus]] band.
