Abstract
The R-matrix method is employed to calculate the total cross section for electron-impact excitation of the and transitions in neutral oxygen. Nineteen spectroscopic states together with 12 pseudo-states are included in the R-matrix wavefunction expansion. The pseudo-states are chosen to ensure that the static dipole polarizability is fully included for all of the three transition states. Although the present calculation is the largest ever performed for neutral oxygen, discrepancies are found for all three transitions between the present theoretical results and experimental data. It is essential that further experiments be performed.Keywords
