The polarization of the G4068 1 16 protons was determined by the asymmetry of their G4068 1 17 scattering in the spark chamber telescope. Events with G4068 1 18 stopping of a proton in the spark chamber were G4068 1 19 recorded by coincidence of the pulses of two G4068 1 20 scintillation counters and anticoincidence of one G4068 1 21 scintillation counter.
