We have calculated atomic data such as energy levels, transition wavelengths, oscillator strengths, transition rates, lifetimes and Collision cross-section for Sn13+ and Sn14+ ions. We have employed Flexible atomic code (FAC) in our computations. We have computed lowest 50 and 17 fine structure levels for Sn13+ and Sn14+ respectively. We have provided transition data for all electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2) and magnetic quadrupole (M2) transitions among lowest 17 levels and 50 levels for Kr-like Sn and Rb-like Sn respectively. We have also provided lifetimes of states of Kr-like and Rb-like Sn ions and predicted that magnetic dipole transitions have dominant contribution in lifetimes of states having large lifetime. We have also reported collision cross-section for Kr-like and Rb-like Sn from ground state to lowest 17 levels and 50 levels respectively. We have compared our calculated data with available theoretical and experimental results and discussed difference between them.

Sn13+ 和 Sn14+ 离子的跃迁数据和碰撞激发截面对激发能量的双重和三重激发态的贡献

我们已经计算了原子数据,例如 Sn 13+和 Sn 14+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 Sn 13+和 Sn 14+ 的最低 50 和 17 精细结构水平分别。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 17 个能级和 50 个能级之间的跃迁数据,分别为 Kr-like Sn 和 Rb-like Sn。我们还提供了类 Kr 和类 Rb Sn 离子状态的寿命,并预测磁偶极跃迁对具有大寿命的状态的寿命有主要贡献。我们还分别报告了类 Kr 和类 Rb Sn 从基态到最低 17 能级和 50 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。
