Abstract
We present the analysis of the data on reactions pp̄ annihilation into three pseudoscalar mesons. The combined analysis of the data taken with liquid hydrogen, gaseous hydrogen and deuteron targets shows an excellent agreement for the reactions investigated and allows to control the fraction of the P‐wave annihilation. The latter provides a better determination of tensor and vector states situated close to the edge of the phase volume. A possible presence of a0(1290) is investigated.
