摘要：

Results of systematic measurements of the asymmetry parameter in the elastic scattering of pions on polarized protons at 1.4-2.1 GeV/c in the backward hemisphere are presented together with a test of the isospin invariance of the data set available on pion-proton scattering in the investigated momentum range. The transversity isodoublet amplitudes at 1.98 and 2.07 GeV/c are reconstructed. The obtained data, the isospin analysis and amplitude reconstruction results are compared with the current phase-shift analysis predictions. © 1991.
