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 quasitemperature of the channeled particle subsystem in steady state, its quasiequilibrium energy distribution, and the diffusion coefficient of the particles.
