Abstract
Excited states in the highly neutron-deficient nuclei 158 W and 152 Yb have been observed for the first time in recoil-decay tagging experiments at the University of Jyvaskyla Accelerator Laboratory using the JUROGAM and GREAT spectrometers in conjunction with the RITU gas-filled separator. The level scheme in 158 W has been established for the first time in a recoil-decay tagged γγ-coincidence analysis. The ground state band is established up to Iπ = 6+, which is the maximum spin permitted for a seniority ν = 2 νf7/2 configuration. Excited states have also been established on the alpha-decaying 8+ isomer and interpreted in terms of ν = 4 configurations. The previous studies of the 152Yb (N = 82) have identified isomeric states corresponding to Jπ = 10+ . These states are thought to be based on two fully aligned h11/2 protons possessing seniority ν = 2. The excited states above isomeric 10+ states were for established for the first time by successive breaking and aligning of the πh11/2 having ν = 4 seniority.
