摘　　要：This paper utilizes multireference configuration interaction theory to calculate the lifetime of A2Пu state for nitrogen molecular ion N2＋. It obtains the transition moment function for A2Пu →X2∑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 its for v′ = 0, 1, 2, 3, 4, 5 vibrational levels of A2Пu state, respectively, which are in excellent agreement with available experimental values.This paper utilizes multireference configuration interaction theory to calculate the lifetime of A2Пu state for nitrogen molecular ion N2＋.
