O113200100017 HISTORY (20040216C) O113200100018 (20040512U) Last checking has been done. O113200100019 SAMPLE A small CH(2) targets, 10*10*5.0-mm**3 was used. O113200100020 DETECTOR (TELES,SCIN,SCIN) Two scintillators 5*5-cm**2 and O113200100021 8*8-cm**2 detected P-P elastic scattering events in O113200100022 coincidence. O113200100023 COMMENT -By authors. The scattering angle of 90-degree-cm was O113200100024 chosen since cross section has a minimum there and O113200100025 effects due to residual vertical polarisation are O113200100026 eliminated. O113200100027 ERR-ANALYS (ERR-S) The uncertainty is reported by authors in O113200100028 table is statistical error. O113200100029 (ERR-1) Systematic uncertainties from the fraction of O113200100030 the incident beam hitting the CH(2) target, the O113200100031 transmission of the scintillation detectors for protonO113200100032 energy, the transmission of the target material. O113200100033 (ERR-2) The error in the target thickness . O113200100034 (ERR-3) The error for particle losses in the CH(2) O113200100035 target and detectors for the scattered protons. O113200100036 (EN-ERR) The error is reported by authors. O113200100037 FACILITY (SYNCY,2SWTVIL) O113200100038 METHOD (EXTB) The used beam originates from 8 degree O113200100039 scattering by a thin Be target of the primary 592 MeV O113200100040 proton beam, which is pulsed at a frequency of 51 MHz. O113200100041 It is focused on a Cu degrader, purified by a O113200100042 deflecting magnet and focused on the target position.
