Total cross-section measurements of the \u3c0+p\u2192\u3c0+\u3c0+n reaction at pion kinetic energies of 180, 184, 190, and 200 MeV are reported. The threshold value for the amplitude a(\u3c0+\u3c0+) as well as the s-wave, isospin 2, \u3c0\u3c0 scattering length a20 were determined. The results were found to be in agreement with chiral perturbation theory and inconsistent with the calculations of Jacob and Scadron and the model of dominance by quark loop anomalies
