The polarization of the G406800100016 protons was determined by the asymmetry of their G406800100017 scattering in the spark chamber telescope. Events with G406800100018 stopping of a proton in the spark chamber were G406800100019 recorded by coincidence of the pulses of two G406800100020 scintillation counters and anticoincidence of one G406800100021 scintillation counter.
