An isomer with a half-life of 15[plus minus]1 [mu]s has been observed in the [ital N]=74 nucleus [sup 136]Sm, populated following the reaction [sup 107]Ag([sup 32]S,[ital p]2[ital n])[sup 136]Sm. It is proposed to have a [ital K][sup [pi]]=8[sup [minus]] two quasineutron configuration. The isomer decays via a [Delta][ital K]=8, 466 keV [ital E]1 transition with a surprisingly low hindrance per degree of [ital K] forbiddenness, [ital f][sub [nu]]=25.
