Abstract We have calculated atomic data such as energy levels, transition wavelengths, oscillator strengths, transition rates, lifetimes and Collision cross-section for Sn3+ and Sn4+ ions. We have employed Flexible atomic code (FAC) in our computations. We have computed lowest 31 and 17 fin. structure levels for Sn3+ and Sn4+ resp. We have provided transition data for all electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2) and magnetic quadrupole (M2) transitions among lowest 31 levels and 17 levels for Ag-like Sn and Pd-like Sn resp. We have also reported collision cross-section for Ag-like and Pd-like Sn from ground state to lowest 31 levels and 17 levels resp. We have compared our calculated data with available theoretical and experimental results and discussed difference between them. Extremely large lifetime of 4d95 s levels of Sn4+ ion is predicted in this work.

Sn3+ 和 Sn4+ 离子的能级、跃迁数据和碰撞激发截面

摘要 我们已经计算了原子数据，例如 Sn3+ 和 Sn4+ 离子的能级、跃迁波长、振荡器强度、跃迁率、寿命和碰撞截面。我们在计算中采用了灵活的原子代码 (FAC)。我们计算了最低的 31 和 17 鳍。Sn3+ 和 Sn4+ 的结构水平。我们提供了所有电偶极子 (E1)、磁偶极子 (M1)、电四极子 (E2) 和磁四极子 (M2) 在最低 31 能级和类银 Sn 和 Pd 类 Sn 的 17 能级之间的跃迁数据。我们还报告了类 Ag 和类 Pd Sn 从基态到最低 31 能级和 17 能级的碰撞截面。我们将我们的计算数据与可用的理论和实验结果进行了比较，并讨论了它们之间的差异。
