摘要：

The ITEP-PNPI collaboration presents the first results of the spin rotation parameter A(+) measurements in the second resonance region. The experiment was performed at the ITEP accelerator at a positive pion beam momentum 1.43 GeV/c for scattering angles theta(m) = 127 degrees and 133 degrees. The setup was based on a polarized proton target and a carbon-plate polarimeter. The obtained data is compared with the predictions of the existing partial-wave analyses.
