The metastable atoms produced by the photodissociation of are detected by observing the enhanced fluorescence of the transition - in the buffer gas xenon. The photodissociation experiments are carried out under conditions of low-pressure (about 100 mtorr) in high-pressure Xe (20-200 torr). The fluorescence spectrum of ) in the wavelength region 510-560 nm is measured. A strong production of is found at wavelengths between 120 and 140 nm in the state, and a small production observed in the range 105-120 nm. Both spectra seem continuous. The Rydberg states in this wavelength region produce very little O(1S).
