In order to analyze multiparticle reactions in which a small number of particles are created, it is necessary to ensure that model multiparticle amplitudes are properly unitarized. Multiparticle partial-wave amplitudes can be thought of as elements in a multiparticle Hilbert space; it is shown how to modify the lengths of model partial-wave amplitudes so that they will satisfy inelastic unitarity conditions.
