Dissociative and double photoionization cross sections of NO from threshold to 120 Å.

The partial photoionization cross sections for producing the NO+ parent ion and the O+, N+, and NO2+ fragment ions from neutral NO are presented from 120 to 614 Å. The results indicate predissociation of the c 3Π (21.72 eV) and B’ 1Σ+ (22.73 eV) electronic states of NO+. The photoionization threshold for double ionization was found to be 39.4±0.12 eV.
