“…The correctness of 0-+, P+ is confirmed by the fact that the results of E10, 12] and of the present work agree with the data of other experiments at the same or nearby energies. As to the values %, the results [21] can be compared with the data of another experiment [23] only using the interpolation procedure. Such a comparison shows reasonable agreement between [21] and [23] for the energies E~=(490+580) MeV.…”

The polarization parameter Po has been measured in the discussed energy range in one experiment [22], so checking by direct comparison of different experimental data is impossible.…”

This paper presents the results of an experiment in which the polarization parameter P in ~+p elastic scattering has been measured in the energy range from 335 to 580 MeV. The experiment was performed on a pion channel of the LNPI synchrocyclotron using a polarized proton target and wire spark chambers with magnetostrictive read-out The results have substantially higher precision in comparison with the most of other experiments in this energy range and allow to determine unambiguously the shape of angular dependence P(O*) in the whole investigated region. New phase-shift analysis of ~+p scattering data has been performed. The results of this experiment were used also to check isospin invariance.
