Abstract: (APS)
High-spin states have been studied in the very neutron deficient N=74 nucleus, Sm136 with the reaction Ag107(32S,p2n)136Sm. Using time-correlated charged-particle–γ–γ spectroscopy, a rotational cascade built upon the t1/2=15 μs, Kπ=8− isomer has been identified. Although equivalent isomers are known in other 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+[404]⊗9/2−[514] two quasineutron assignment. A second high-K band, probably of a four-quasiparticle nature, is observed to feed into the Kπ=8− band.- 27.60.+j
