利用扩展的组态相互作用波函数，计算了S III的3s23p2、3s3p3、3s23p3d、3s23p4s、3s23p4p和3s23p4d组态的精细结构能级跃迁的振子强度和跃迁几率。利用Breit-Pauli哈密顿量考虑了中间耦合中的相对论效应。对哈密顿矩阵的对角元素作了较小的调整，使能量分裂尽可能接近实验值。本文的计算结果与已有的计算和实验结果进行了比较。
Oscillator strengths and transition probabilities for transitions among the fine-structure levels of the terms belonging to the 3s23p2, 3s3p3, 3s23p3d, 3s23p4s, 3s23p4p, and 3s23p4dconfigurations of S III are calculated using extensive configuration-interaction wave functions. The relativistic effects in intermediate coupling are incorporated by means of the Breit–Pauli Hamiltonian. Small adjustments to the diagonal elements of the Hamiltonian matrices have been made so that the energy splittings are as close as possible to the experimental values. The present results are compared with other available calculations and experiments.
