    High-resolution experiments and B-spline R-matrix calculations for elastic electron scattering from krypton

    Zatsarinny, O. ; Bartschat, K. ; Allan, Michael

    In: Physical Review A: Atomic, Molecular, and Optical Physics, 2011, vol. 83, no. 3, p. 032713

    In a joint experimental and theoretical effort, we carried out a detailed study of elastic electron scattering from Kr atoms. Absolute angle-differential cross sections for elastic electron scattering were measured over the energy range 0.3-9.8 eV with an energy width of about 13 meV at scattering angles between 0° and 180°. Excellent agreement is obtained between our experimental data and...

    Electron impact excitation of the (4p⁵ 5s) states in krypton: high-resolution electron scattering experiments and B-spline R-matrix calculations

    Allan, Michael ; Zatsarinny, O. ; Bartschat, K.

    In: Journal of Physics B: Atomic, Molecular and Optical Physics, 2011, vol. 44, no. 6, p. 065201

    In a joint experimental and theoretical effort, we carried out a detailed study of electron impact excitation of the 4p⁵ 5s states of Kr. We present angle-differential cross sections over the entire angular range (0°–180°) for a number of energies in the near-threshold region, as well as energy scans for selected angles. The experimental results are in very satisfactory agreement with...
