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 () 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
(coplanar symmetric geometry) and
(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
caused by the single collision mechanism has been observed in
the perpendicular plane geometry. The TDCSs at the gun angles
, and
are predicted.
