Abstract
It is shown that the non-Fermi-liquid state is unstable with respect to scattering of multiparticle excitations with different quantum numbers by one another. As a result of the scattering, a multiparticle Fermi-liquid resonance forms at the Fermi level. An anomalous increase in the conductivity occurs as a result of a transition between the non-Fermi-liquid and Fermi-liquid states.Keywords
