    Absolute angle-differential cross sections for excitation of neon atoms to the four 2p⁵3s and to selected 2p⁵3p levels have been determined as a function of electron energy up to 3.5 eV above threshold at the scattering angles of 0°, 45°, 90°, 135° and 180°. In addition, the cross sections were recorded as function of scattering angle from 0° to 180° at 18 eV for the 2p⁵3s levels and...

    Absolute angle-differential cross sections for electron-impact excitation of neon atoms from threshold to 19.5 eV

    Allan, Michael ; Franz, K. ; Hotop, Hartmut ; Zatsarinny, O. ; Bartschat, K.

    In: Journal of Physics B: Atomic, Molecular and Optical Physics, 2006, vol. 39, p. L139-L144

    Absolute angle-differential cross sections for electron-impact excitation of neon atoms to the four levels with the (2p⁵3s) configuration have been determined both experimentally and theoretically for incident energies from threshold up to 19.5 eV at scattering angles of 135° and 180°. Excellent agreement between the experimental data and theoretical predictions, obtained by a Breit–Pauli...
