Kallman, T. ; McCray, R. Abstract A simplified theory of the Bowen resonance fluorescence mechanism is presented for both the pumping of the O III Bowen lines by He II 304 A and for the pumping of the N III Bowen lines by O III 374 A. Theoretical results, calculated on the basis of an escape probability approximation for resonance line transfer, obey simple scaling laws. The O III Bowen fluorescence yields calculated for a model planetary nebula agree well with those obtained in more rigorous calculations by Weymann and Williams and by Harrington. Intensities of O III and N III Bowen lines observed in the spectra of planetary nebulae and compact X-ray sources are discussed.
