Auger relaxation in 2D strongly correlated electron gas can be represented asan Auger-like process for neutral magnetoplasmon excitations. The case of"dielectric" state with lack of free electrons (i.e. at integer filling $\nu$)is considered. Really the Auger-like process is a coalescence of twomagnetoplasmons which are converted into a single one of a different plasmonmode with zero 2D wave-vector. This event turns out to be energetically allowedfor magnetoplasmons near their roton minima where the spectrum has the infinitedensity of states. As a result the additional possibility appears for indirectobservation of the magnetorotons by means of anti-Stokes Raman scattering. Wefind the rate of this process employing the technique of ExcitonicRepresentation for the relevant matrix element calculation.
