On the theory of light scattering by a dilute gas Bose—Einstein condensatea Institute of Precision Mechanics and Control, Russian Academy of Sciences, ul. Rabochaya 24, Saratov, 410028, Russian Federation b Herzen Russian State Pedagogical University, nab. r. Moiki 48, St. Petersburg, 191186, Russian Federation The semiclassical theory of light scattering by a dilute gas Bose—Einstein condensate is examined with special attention paid to the key role of the momentum recoil imparted to atoms by photons, a phenomenon that disturbs the interference quenching of superradiant scattering.
