Electron-impact excitation of the and states of neon

Abstract

We performed a 31-state semi-relativistic Breit - Pauli R-matrix calculation for electron-impact excitation of neon. The calculated energy levels were found to be very accurate. Results are presented for angle-integrated cross sections in the energy range from threshold to 30 eV for the and states, together with some selected differential cross sections. These predictions are compared with experimental and other theoretical data. A strong dependence of the near-threshold resonance structure and the cross section results on the details of the structure calculation is found.
