<blockquote>
Within the reference system approach a method of calculation of plasmons
excitations spectrum for the electron liquid model is proposed. It was
made by transition from Matsubara's frequency representation to Heisenberg's
one and to the mixed representation for the many-particle dynamical 
correlation functions of the reference system (ideal degenerated electron
system) and for the dynamical local field correction. For the ground state
of model the plasmon dispersion curves are investigated in the wide region
of the coupling parameter r_s.
