摘要：

An analysis has been made of all available data near threshold for the reactions pi-N --> pi-pi-N in terms of isospin amplitudes. The experiments for different channels are found to be consistent with each other and with the chiral-symmetry-breaking model of Olsson and Turner. The analysis yields values for the pi-pi scattering lengths which are in good agreement with a calculation based on the Weinberg pi-pi interaction corrected for the effects of the f0(975) scalar meson.
