Author(s): M.V.Vavrukh, N.M.Vavrukh, T.E.Krokhmals'kii, V.B.Solovjan

One of the fundamental characteristics of degenerated interacting electron gas, local-field correction, is investigated in wide region of the coupling parameter. Previously developed by the autors reference system approach is applied. Numerical solutions of the system of non-linear integral equations, defining local-field correction in static and dynamic cases are obtained. It is shown that the form of static local-field correction changes depending on the coupling parameter value near the point q = 2kF. For weakly coupled systems the curves have the peak near this point and monotonic behaviour is observed in the low electron densities region.
