摘要
The interaction of light quarks and instanton liquid is. analyzed at finite density of quark/baryon matter and in the phase of nonzero values of diquark (colour) condensate. It is shown that instanton liquid perturbation produced by such an interaction results in an essential increase of the critical value of quark chemical potential mu(c) which proyokes the perceptible increase of quark matter density around the expected onset of the colour superconductivity phase.
