Abstract

The state-selective non-dissociative single-electron capture reactions of 6 keV NO2+ ions from noble gas (He, Ne, Ar, Kr and Xe) targets are investigated by translational energy spectroscopy. Capture occurs predominantly from ground state NO2+ (X 2Σ+). For the NO+ (X 1Σ+) formation a shift of the peak in the translational energy distribution was found (1.3 to 1.7 eV) which suggests higher vibrational excitation of the molecular product than expected from the mutual position of potential energy curves of the NO system. A simple model assuming a dynamical perturbation of the NO+ curve in the presence of He+ is suggested, which accounts for the shift.
