Title: Valence-shell autoionization of NO

Abstract

Autoionization of valence and Rydberg states in NO over the 12.5-18 eV photon energy range was studied by vibrationally resolved photoelectron spectroscopy of the 2 π orbital. Complex, oscillatory structure is observed in NO + (2 π 01) Χ 1 Σ + partial cross sections, branching ratios, and photoelectron anisotropy parameters due to autoionizing valence states and Rydberg states associated with the 1 π -1 and 5 σ -1 channels. Autoionization of the 5 σ → np(π, σ) (υ' = 0), n = 3-5 Rydberg states leading to the (5σ -1) b 3 Π state of NO + produces very high vibrational levels of (2 π -1) Χ 1Σ +. Autoionization of the 5 σ → 3 p π (υ' = 0) Rydberg state was characterized by resonance profiles of photoelectron cross sections and angular distributions.
