Particle?s method for the model of the electromagnetic field of electron?s flux in gas

The kinetic equation for electrons in the neutral medium and self-consistent electromagnetic field is considered. The integral of collisions in the approximation of small energy transfers is constructed. The approximate solution of the kinetic equation, which allows using particles method for numerical simulation of the electric current density, is suggested. The smallness of the pulse transfer in collisions and cross-section increasing with electron?s energy decrease are used.
