摘要：

The theory on Coulomb collisions in plasmas has been previously presented [K. Nanbu, Phys. Rev. E 55, 4642 (1997)]. The theory is based on the relaxation equation for the scattering angle and the model equation for the probability density function of the scattering angle. The validity of both equations was ascertained by numerical simulations in the above paper. It is shown that the first equation, which describes the relaxation of the momentum of a particle, can be derived analytically.
