A line of an LO-phonon repetition of hot luminescence has been observed during resonant laser pumping of Znj _ ^Mn^Se. In a magnetic field, a component splits off from this line. This component is shifted by the energy of the giant spin splitting of the conduction band. The effect is attributed to a fast relaxation of excitons due to an exchange scattering by spins of shallow donors.
