摘要：

The possibilities of extracting parameters of pi-pi interaction from the experimental data on the pi-N --> pi-pi-N reaction are analyzed in detail. The interval 300 < P(lab) < 500 MeV/c is shown to be the smoothness domain of the pi-N --> pi-pi-N amplitude. The expression for the background part of the amplitude is developed model-independently. The pi-pi scattering is described by four parameters to be extracted from experimental data (along with 11 background parameters).
