Abstract

High-resolution translational-energy spectrometry has been applied to study vibrational excitation in neutral CO2 in its ground electronic state by 3 ke V impact by O+, N+, Ne+, Ar+ and Xe+ projectile ions. Three quanta of asymmetric stretch mode are excited. Bending mode vibrational excitation also manifests itself in translational-energy spectra obtained with the heavier projectile ions (Ne+, Ar+ and Xe+). In the case of the O+ projectiles, simultaneous electronic (O+,2D⇔ 2P) and vibrational (CO2, V3=0→ 1) excitation is also observed.
