本文对产生于4d105sns(n=6-9)、4d105Snp(n=5，6)、4d105p2、4d105sd(n=5-7)、4d105s4f和4d105s5g组态的171条谱线的振子强度和跃迁几率进行了理论计算，并计算了36能级的辐射寿命。这些值是在中间耦合(IC)中使用相对论Hartree-Fock计算得到的，其中包括势中的核-极化效应和矩阵元素中的相应修正。对于IC计算，我们使用标准的最小二乘法，通过Cowan计算机程序从实验能级进行拟合。在这些计算中，4d95s25p的包含使我们可以对SnIII的能级进行新的指认。得到的跃迁几率、振子强度和辐射寿命与实验数据符合得很好。
This paper contains the results of theoretical calculations of oscillator strengths and transition probabilities of 171 spectral lines arising from 4d105sns (n = 6–9), 4d105snp (n = 5, 6), 4d105p2, 4d105snd (n = 5–7), 4d105s4f and 4d105s5g configurations, and 36 level radiative lifetimes of Sn III have been calculated. These values were obtained in intermediate coupling (IC) and using relativistic Hartree–Fock calculations including core-polarization effects in the potential and the corresponding corrections in the matrix elements. We use for the IC calculations the standard method of least-squares fitting from experimental energy levels by means of the Cowan computer code. The inclusion in these calculations of the 4d95s25p has allowed us to make a new assignment of the energy levels in Sn III. Transition probabilities, oscillator strengths and radiative lifetimes obtained are in good agreement with the experimental data.
