Contribution of doubly and triply excited states in excitation energies with transition data and collisional excitation cross-section of Sn13+ and Sn14+ ions

Abstract

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.
