Abstract.

 The strong decays of mesons are studied in the framework of the 3 P 0 model with a momentum-dependent vertex. The meson wave functions are obtained from quark-antiquark potentials including a finite quark size, instanton effects, spin-orbit and tensor-force effects. Several prescriptions for treating the decays into three mesons are proposed and analyzed. Comparison to experimental data is presented in detail.
