| Abstract | ||
| A formula for the total ionization cross section by electron impact were employed and it based on binary collision ,i.e., the independent pair interactions of the individual elements of the colliding system. The theory is applied to molecules of interest in many scientific fields. Total ionization cross sections of 6-molecules, CF, CF2, CF3, SF3, SF5, and SF6, are presented for incident electron energies from threshold to 1KeV. The cross sections are presented in a compact analytic form with a small number of constants, making the cross sections suitable for modeling applications. Our results agree with the experimental data very well in some energy ranges when the cross section decreases after reaching the peak, also it has the same behavior of the theoretical data of the Binary-Encounter-Bethe (BEB)-model, which had been compared with. | ||
