We find the permittivity of a degenerate electron gas for a collisional plasma. We use the Wigner–Vlasov–Boltzmann kinetic equation with the collision integral in the relaxation form in the coordinate space. We study the Kohn permittivity singularities and reveal their spreading in the collisionless plasma.
Keywords: degenerate electron gas, permittivity, collision integral, Lindhard function, Kohn singularity.
