N2 - We have studied the time-resolved spectra, the energy-resolved spectra, and the total intensity of light emission induced by near-resonance two-photon excitation to the 4D322 and 4D522 levels of Na over the detuning range -7 cm-1<~Δ<~7 cm-1. The time-resolved spectra of Na perturbed by Ar exhibit a fast adiabatic component and a slow resonance-fluorescence component. The cross section for phase-shifting, T2-type collisions in this atomic system is σ=110±20 2.
