The experiments were performed under coplanar asymmetric kinematics, at intermediate incident electron energies, and for a range of scattered electron detection angles. The experimental results are compared with three calculations: a convergent close-coupling calculation, a distorted-wave Born approximation (DWBA) calculation with inclusion of the Gamow factor, and a hybrid DWBA+R -matrix calculation. The comparison between the experimental and theoretical results highlights the importance of the description of postcollision interaction, and the results exhibit interesting orbital-dependent differences.Keywords: Approximation theory; Born approximation; Electron scattering; Electrons; Inert gases; Ionization; Neon; Xenon; Convergent close-coupling calculations; Distorted waves; Electron-impact ionizations; Fully differential cross sections; Fully differentials; I200910.1103/PhysRevA.79.0127092016-02-24
