We develop a theory to calculate exciton binding energies of both two- andthree-dimensional spin polarized exciton gases within a mean field approach.Our method allows the analysis of recent experiments showing the importance ofthe polarization and intensity of the excitation light on the excitonluminescence of GaAs quantum wells. We study the breaking of the spindegeneracy observed at high exciton density $(5 \ \ 10^{10} cm ^2)$. Energylevel splitting betwen spin +1 and spin -1 is shown to be due to many-bodyinter-excitonic exchange while the spin relaxation time is controlled byintra-exciton exchange.Comment: Revtex, 4 figures sent by fax upon request by e-mai
