Shape resonant features in the photoionization spectra of NO

Abstract

Calculations of core and valence level photoionization spectra of NO are presented and compared with available experimental data. A low‐lying continuum shape resonance is identified in the σ photoionization channel, which is the analog of similar states found in other first‐row diatomic molecules. Both partial cross sections and photoelectron angular distributions are discussed, and the effect of nuclear motion on these observables is treated.
