Description

High spin states of 125Sb have been investigated for the first time by means of in-beam γ-ray spectroscopy techniques via the 124Sn(7Li, α2n) reaction at 32 MeV beam energy. Based on the measurements of γ-γ coincidence and γ-ray anisotropies, a level scheme including 21 new γ-transitions and 14 new excited levels was established up to 23/2+. Three isomers at 1970, 2110 and 2471 keV levels have been identified and proposed as three-quasiparticle πg7/2ν(h11/2s1/2), πg7/2ν(h11/2d3/2) and πg7/2ν(h11/22) configurations, respectively. The level structure of 125Sb is discussed in terms of particle-core coupling
