ResumoThe effect of interaction in the final state on the angular distribution in reactions involving the formation of three low energy particles is considered. In the case of non-resonance interaction the angular distribution can be expressed in terms of scattering amplitudes of pairs of particles. It is shown how the meson-meson scattering amplitudes can be deduced from the angular distribution of the decay products of the τ+ → 2π++π−, τ+ → 2π0+π+ reactions. Experimental data presently available are insufficient for determining these amplitudes.
