On the Coefficients of Irreversible Processes in a Highly Ionized Gas

抄録

An effective interparticle potential, which is a modified Debye-Hückel potential, is introduced and discussed in order to eliminate simultaneous interactions between three particles or more in an ionized gas. For this potential weak-interaction asymptotes of collision cross sections necessary for the theory of irreversible processes are calculated without making further approximations. These cross sections are applied to relaxation between ion and electron temperatures and to the coefficient of viscosity.
