Previously developed method for finding asymptotic solutions of Vlasov equations using two-dimensional (in coordinate x and time t) Laplace transform is applied to low-collision electron-ion plasmas. Taking into account Coulomb collisions in the limit me << mi, vi << ve, and Te me << Ti mi, results in the expression for longitudinal high-frequency plasma-electron oscillation/wave decrement essentially depending on oscillation frequency ω. This expression is quite different from the used one for low-frequency plasma sound, which can be derived using expansion in asymptotically divergent series in δ/ω0, k vi/ω0, where δis imaginary part of the frequency ω=ω0+iδ, and does not reduce to simple expression with some collision frequency δ∼νeffei.
