Determination of the Total Particles Collision Frequency For Diffusion Electrons in Argon Gas

In this work we calculated the atom-electron collision frequency, ion-electron collision frequency and total collision frequency for electron diffused in gaseous media for Argon gas at temperature 300 0k and total gas number density, N=2.55x1019 cm-3, where solved numerically transport equation in gaseous medium after applied electric field, E/N (strength electric field to total gas number density ratio) at the values (1 E/N 10)x10-18 V cm2, since we obtained the following values: drift velocity ,Vd electron average , u and electrons collision frequency with atoms, and fed these data to the derivate equations (calculations item) and from these we calculated the total frequency further more . We calculated the electron complex admittance ratio by using MathCAD program, version 2001. The results which obtained a papered a good agreement with experimental and theoretical literature.
