Electron Collision Excitation of Metastable Levels in N I, N II, O I, O II, O III.
Abstract
Electron impact excitation cross sections have been calculated for transitions between terms of the ground configuration of neutral and ionized nitrogen and oxygen. The cross sections have been obtained by a distorted wave approximation and the accuracy of the results is estimated by a comparison with the close-coupling method and with the exact-resonance approximation. For neutral nitrogen and oxygen, the DW method is improved by the inclusion of a polarization potential with a cut-off parameter, which is determined from the variation condition. Excitation rates have been computed for temperatures from 1,000 to 1,500,000K.
