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

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. •Energy levels and lifetimes of lowest 50 and 17 levels of Sn13+ and Sn14+ resp. are presented.•Radiative data for E1, E2, M1 and M2 transitions for Sn13+ and Sn14+ are provided.•Collisional excitation cross-section for Sn13+ and Sn14+ from ground state are reported.•Contribution of doubly and triply excited states on excitation energies of Sn 13+ and Sn14+ are studied.
