Abstract

Laser multiphoton ionization spectroscopy of highly excited {ng} Rydberg states (n=11-67, $\nu$=0 and 1) of NO was performed. Three-color triple resonance technique was used for rotationally state selective excitation of high {ng} Rydberg states. The observed term values were well reproduced by theoretical calculation based on the long range force model. The experimental evidence for fast autoionization decay in the {ng} Rydberg slates, which has been theoretically predicted, was found at first. Not only autoionization, but also predissociation decay was observed.
