Energy levels, radiative rates and lifetimes are reported for four S-like ions, namely Sc VI, V VIII, Cr IX, and Mn X. Two independent atomic structure codes, namely the general-purpose relativistic atomic structure package (grasp) and the flexible atomic code (fac), have been adopted for calculating the energy levels, with differing amounts of configuration interaction. This is mainly to make some assessment of accuracy. However, the grasp alone is used for calculating the remaining parameters. Results are reported for varying number of levels of these ions, and for calculating lifetimes contributions are included from all types of transitions, i.e. E1, E2, M1, and M2. Comparisons are made with the earlier available experimental and theoretical results and assessments of accuracy are given for each ion. Additionally, the presently reported data cover a significantly larger number of levels and transitions than already available in the literature for the four S-like ions.

报告了四个类S离子（Sc VI，V VIII，Cr IX和Mn X）的能级，辐射速率和寿命。两个独立的原子结构代码，即通用相对论原子结构包（“掌握”）和“原子结构”。灵活的原子代码（fac）已被用于计算能量水平，具有不同数量的配置相互作用。这主要是为了对准确性进行一些评估。但是，掌握单独用于计算其余参数。报告了这些离子的不同数量水平的结果，并且为计算寿命，还包括了所有类型的跃迁（即E1，E2，M1和M2）的贡献。与较早的可用实验和理论结果进行了比较，并给出了每种离子的准确度评估。此外，目前报道的数据涵盖的水平和跃迁数量明显多于文献中四个类S离子的水平和跃迁。
