摘要: This paper utilizes multireference configuration interaction theory to calculate the lifetime of A2\Pi _{\rm u} state for nitrogen molecular ion N_{2}^{ + }. It obtains the transition moment function for A2\Pi _{\rm u} \to x2\Sigma g^{ + }, Franck--Condon factors between vibrational levels of the two states. The calculated lifetimes are 16.81, 14.62, 13.10, 12.18, 11.40, and 11.64~μ s for v'=0, 1, 2, 3, 4, 5 vibrational levels of A2\Pi _{\rm u} state, respectively, which are in excellent agreement with available experimental values.
