Abstract

The distorted wave Born approximation (DWBA) with the spin averaged static exchange potential has been used to calculate the triple differential cross-sections (TDCSs) for Ne ( $2s^2$ ) ionization by electron impact in coplanar to perpendicular plane symmetric geometry at 110.5 eV incident electron energy. The present theoretical results at gun angles $\Psi = 0^\circ$ (coplanar symmetric geometry) and $\Psi = 90^\circ$ (perpendicular plane geometry) are in satisfactory agreement with the available experimental data. A deep interference minimum appears in the TDCS in the coplanar symmetric geometry and a strong peak at scattering angle $\xi = 90^\circ$ caused by the single collision mechanism has been observed in the perpendicular plane geometry. The TDCSs at the gun angles $\Psi = 30^\circ$ , and $\Psi = 60^\circ$ are predicted.
