The Completion of Single-Spin Asymmetry Measurements at the Proza Setup

Single spin asymmetry in inclusive $pi^0$-production was measured in the polarized target fragmentation region using 50 GeV proton beam. The asymmetry is in agreement with asymmetry measurements in the polarized beam fragmentation region carried out at higher energies. The measurement completed 30-years history of polarized measurements at the PROZA setup.
