The generalized distribution of electrons in energy and momentum is calculated in a nonideal plasma in a strong laser field. It is shown that the non‐equilibrium generalized distribution leads to the power tails in the electron momentum distribution and a steep exponential rise in the rates for electron threshold processes. Taking into account the Pauli blocking shows a drastic rise in the rates in a strong laser field (for non‐equilibrium distribution). An equation for the energy and momentum‐dependent collisional width is derived in the Lorentz approximation. The numerical solution of this equation is used to calculate the momentum distribution function.
