We have presented a theoretical analysis of atomic parameters such as excitation energies, lifetimes, and radiative transition parameters of Sn12+ ion and discussed discrepancy with theoretical and experimental results. We have also studied collisional excitation of Sn12+ for the lowest 9 states at six different scattered electron energies and photoionization cross sections of 4d and 4d2 states of Sn13+ and Sn12+ ions at five different photo-electron energies by employing distorted wave method in our computational procedure. We have provided transition data for multipole transitions. We analyzed the lifetimes of all states of Sn12+ and predicted that the lifetimes of 4d2 and 4p54d3 states are large as compared to the lifetimes of other states.
