title: Kinetics of ensembles with variable charges.
abstract: Kinetics of particle ensembles with variable charges is investigated. It is shown that the energy of such ensembles is not conserved in the interparticle collisions. The case when the equilibrium charge depends on the particle coordinate is studied, and the collision integral describing the momentum and energy transfer in collisions is derived. Solution of the resulting kinetic equation shows that the system is unstable--the mean thermal energy exhibits explosion-like growth, diverging at a finite time.
