The approach to equilibrium of a system of electrons in a periodic system is studied by deriving a kinetic equation in the self‐consistent field approximation. The derivation based on the introduction of an hierarchy of equations for the s‐body density matrices and employing a truncation scheme, valid in the self‐consistent field approximation. The irreversibility is introduced by the adiabatic hypothesis of Bogoliubov. The kinetic equation takes proper account of the collective aspects of the electron system and includes the dynamic shielding.
