Bowen fluorescence in the solar transition regionIn Bowen fluorescence, a 304-A photon of He II is converted into two optical photons and an EUV photon of O III. The fluorescent contribution to the intensity of the O III 374-A line is a measure of the column density of O III in the solar transition region. Division of the column density into the emission measure derived from other lines of O III allows determination of the electron density. The accuracy of this technique is roughly a factor of 2, which is comparable to the accuracy of the density diagnostics for the solar transition region.
