Abstract
Calculations of cross-sections for the excitation of 3 fine structure levels of the ground P state of atomic oxygen by electron-impact in the energy range 500-15000°K are made in the close-coupling approximation. It is shown that above 3000°K, the exact-resonance approximation can be used to obtain quite reliable results. In this range polarization effects can be incorporated by use of pseudostates. The convergence of the close-coupling expansion has been tested by adding more terms belonging to the same configuration as well as pseudo-states. The effect of using a multi-configuration wave function was examined. Results are presented for a two-configuration wave function.
