Excited states of
125 Sb have been studied using in-beam γ spectroscopy techniques via the124 Sn(7 Li, α2n) reaction at a beam energy of 32 MeV. A high-spin level scheme including 21 new γ-transitions and 14 new excited states have been established. Three isomers have been identified at 1970, 2110 and 2471 keV and the ranges of their half-lives have been estimated from the delayed coincidence data. The level structure of125 Sb is discussed in terms of particle-core excitation coupling. With the help of empirical shell model calculations the three isomers are proposed to have three-quasiparticle πg7/2 ⊗ v( h11/2 s1/2 )5− , πg7/2 ⊗ v( h11/2 d3/2 )7− and πg7/2 ⊗ v( h )10 + configurations, respectively.
