利用在束γ谱学方法,通过124Sn(7Li, α2n)反应首次研究了丰中子核125Sb的高自旋态. 建立了自旋达23/2+、激发能至2637keV的能级纲图 ,其中包括21条新γ跃迁和14个新能级. 在1970,2110和2471keV识别出了3个同质异能态, 估计了它们的寿命范围,并建议分别具有πg7/2ν(h11/2s 1/2 ), πg7/2ν(h11/2d3/2), πg7/2ν (h2 11/2)三准粒子组态. 根据价质子与124Sn核芯激发态的耦合讨论了125 Sb的能级结构.

High spin states of 125Sb have been investigated for the first time by means of in-beam γ-ray spectroscopy te chniques 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 ident ified and proposed as three-quasiparticle πg7/2ν(h11/2 s1/2), πg7/2ν(h11/2d3/2) and π g7 /2ν(h211/2) configurations, respectively. The level structure of 125Sb is discussed in terms of particle-core coupling .
