Calculation of Electron-Impact 2s^2 2p^4 ^3P→2p^3 3s^3S^0 Transition in Atomic Oxygen

The inelastic scattering of electron from oxygen for the 2s^2 2p^4 ^3P→2p^3 3s^3S^0 transirion is studied using the momentum-space coupled channel optical method at 15, 17.5, 20, 22.5, 25, 27.5, 30, 50, and 100eV. Direct ionization cross sections, i.e. differential and integral cross sections, are reported. Important continuum states are included in the coupled channel calculation via a complex equivalent-local optical potential. The present results are compared with the available experimental data and other theoretical calculation results.
