The photoion excitation spectra of 14NO and 15NO have been studied in the 105-112 nm excitation region using
high-order harmonic laser spectroscopy. Utilizing the small bandwidth offered by this technique, the natural widths of
prominent lines in this region have been measured. These lines originate from interactions between high-lying Rydberg
levels converging to the NO + electronic ground state and a 'new' NO valence state situated close to the latter state. The
present measurements show broad resonances corresponding to a decay time of 20-50 fs. This supports the interpretation
that the decay takes place via rapid electronic autoionization.
