Multiparticle symmetrization effects are contributions to the spectra of Bose-symmetrized states which;are not the product of pairwise correlations. Usually they are-neglected in particle interferometric calculations which aim at determining the geometry of the boson emitting source from the measured momentum distributions. Based on a method introduced by Zajc and Pratt, we give a calculation of all multiparticle symmetrization effects to the one-and two-particle momentum spectra for a Gaussian phase-space distribution of emission points. Our starting point san ensemble of N-particle Bose-symmetrized wave functions with specified phase-space localization. In scenarios typical for relativistic heavy-ion collisions, multiparticle effects steepen the slope of the one-particle spectrum fdr realistic particle phase-space densities by up to 20 MeV, and they broaden the relative momentum dependence of the two-particle correlations. We discuss these modifications and their consequences in quantitative detail. Also, we explain how multiparticle effects modify the normalization of the two-particle correlator. The resulting normalization conserves event probabilities, which is not the case for the commonly used pair approximation. Finally, we propose a method of calculating Bose-Einstein weights from the output of event generators, taking multiparticle correlations into account.
