Extreme ultraviolet photodissociative excitation of molecular oxygen

Photodissociation processes in molecular oxygen occurring in the wavelength range from 500 to 900 A, investigated through observations of the resulting atomic fluorescence radiation, are reported. The dispersed radiation from a continuous light source was used to excite the gas, and the resulting fluorescence radiation was observed in the ultraviolet and infrared. The results obtained are compared with the dissociation cross sections derived by Matsunaga and Watanabe (1967).
