Abstract
High-spin states have been studied in the very neutron deficient N=74 nucleus, with the reaction S,p2nSm. Using time-correlated charged-particle–γ–γ spectroscopy, a rotational cascade built upon the =15 μs, = 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/[404]⊗9/[514] two quasineutron assignment. A second high-K band, probably of a four-quasiparticle nature, is observed to feed into the = band.
