A single-color laser-induced collisional charge transfer system of Xe + −N 2 is introduced, and the charge transfer process between Xe + and N 2 is observed. The laser-induced charge transfer (LICT) in Xe + −N 2 system is experimentally investigated through time-of-flight (TOF) mass spectrometry, and the intensity dependence of product ions at ∼440 nm under several different conditions are measured, showing the impacts of laser parameters, mixing ratio, and pressure on the charge transfer process. Our results indicate that the charge transfer process between Xe + and N 2 can be enhanced by the joint action of the collisional and radiative interactions.
