Formulas for longitudinal electric conductivity and dielectric permeabilityin the quantum non-degenerate collisional plasma with the frequency ofcollisions depending on momentum in Mermin' approach are received. The kineticequation in momentum space in relaxation approximation is used. It is shownthat when Planck's constant tends to zero, the deduced formula passes to thecorresponding formula for classical plasma. It is shown also that whenfrequency of collisions of particles of plasma tends to zero (plasma passes tocollisionless one), the deduced formula passes to the known Lindhard' formulareceived for collisionless plasmas. It is shown, that when frequency ofcollisions is a constant, the deduced formula for dielectric permeabilitypasses in known Mermin' formula.
