Abstract

We report both experimental and theoretical differential and integral excitation cross sections of atomic oxygen corresponding to the 2s22p4 3P→3s 3S (130.4 nm), 2s22p4 3P→3d 3D (102.7 nm), 2s22p4 3P→3s' 3D (98.9 nm) and 2s22p4 3P→3s'' 3P (87.8 nm) transitions at 30, 50, and 100 eV electron-impact energies. Experimental measurements have been made in the angular range from 0° to 25° with a conventional electrostatic electron energy-loss spectrometer. The atomic O differential cross sections (DCSs) were put on an absolute scale by normalization to the O2 DCS values of Johnson and Kanik (2001). Extrapolation of the measured results to larger angles was performed using theoretical calculations as a guide, and integral cross sections were derived. Theoretical calculations based on the _R_-matrix method, along with other available experimental data, have been compared with the current experimental results.
