Charged-particle distribution in velocity,angle and time by Fokker-Planck equation

Summary The present paper describes a direct method of obtaining are expression of the distribution function of charged particles which diffuse in a plasma. The distribution function in velocity, angle and time is presented starting from the Fokker-Planck equation. Temperature, average velocity and energy of charged particles (electron or ions) have also been calculated as functions of time. The authors of this paper have agreed to not receive the proofs for correction.
