Abstract

We study the collision frequencies of charged particles in the complex plasmas with the non-Maxwellian velocity distributions. The average collision frequencies of electron-ion, electron-electron and ion-ion are derived in the two-parameter (r,s) and the three-parameter (a,r,s) velocity distributions, respectively. We show that these average collision frequencies in the complex plasmas depend strongly on the parameters in the non-Maxwellian distributions and thus are significant deviations from those in the plasmas with a Maxwell velocity distribution. Numerical analyses are made of the effects of the parameters on the average collision frequencies. The results have important effect on transport coefficients and their properties of charged particles in the highly ionized complex plasmas with the non-Maxwell distributions.
