Electron-impact excitation of the (2p(5)3s) and (2p(5)3p) states of neon

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 (2p(5)3s) and (2p(5)3p) 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 3p'[1/2](0) cross section results on the details of the structure calculation is found.
