NONEQUILIBRIUM STATISTICAL-THEORY OF CHANNELING - ENERGY-MOMENTUM BALANCE EQUATION AND TRANSVERSE QUASITEMPERATURE OF A CHANNELED PARTICLE SUBSYSTEM

Planar channeled particles (protons, helium ions, etc.) are considered as an individual thermodynamic subsystem. A statistical operator for the nonequilibrium system under conditions of multiple electron scattering and an energy-momentum balance equation are obtained on the basis of the nonequilibrium statistical thermodynamics. The formalism presented is applied to analyze the transverse quasi-temperature of the channeled particle subsystem in steady state, its quasiequilibrium energy distribution, and the diffusion coefficient of the particles.
