Abstract: We calculate the quasitemperature of positronium atoms moving in a solid in the framework of nonequilibrium statistical thermodynamics. We represent the quasitemperature in the form of the renormalized temperature of the thermostat. The renormalization results from taking the positronium formation rate, the kinetic effects of interaction, and the dynamical effects of collisions into account. We obtain an expression for the thermalization time of positronium atoms.

Keywords: nonequilibrium statistical thermodynamics, positronium atom, solids, thermodynamic parameters, quasitemperature, transport coefficient, relaxation matrix, thermalization.
