Abstract
A semiclassical theory of superradiant scattering and propagating of light in a Bose-Einstein condensate of dilute atomic vapours is proposed. Choosing atomic states with definite momentum as a basis we derive a nonlinear Schrodinger equation. The solutions of the equation describe the temporal evolution of light intensity and of the populations of the coherent atomic states with different recoil moments.
