Revised cross-section values for the excitation of the O I(3s 3S0--2p 3P; &lgr;1304 ¿) O I(3d 3D0--2p 3P; &lgr;1027 ¿), and O I(3s' 3D0--2p 3P; &lgr;989 ¿) resonance transitions by electron impact on atomic oxygen are presented from threshold to 300 eV. These results are smaller than the excitation cross sections used in some airglow models by a factor of ~2.8. The revised values are in good agreement with recent quantum-scattering calculations. The downward revision is required by new laboratory studies in which the direct and dissociative cross sections for &lgr;1304 ¿ excitation were normalized with small probable error to the O and O2 ionization cross sections. The results also reflect new advances in VUV optical calibration techniques. A number of outstanding airglow problems are simplified by these revisions.
