Scientific paper

The excitation of the triplet lines of O(2+) between 280 and 380 nm in nebulae is attributed to a combination of the Bowen fluorescence mechanism pumped by the He(+) resonance line and charge transfer into excited states of O(2+) in collisions of O(3+) with neutral hydrogen atoms. The lines at 377.4 and 375.7 nm are due almost entirely to charge transfer population of the (2p 3p)3D1 level. The close agreement obtained between the calculated and observed line intensities confirms the accuracy of the charge transfer rate coefficients.
