O121800100018 HISTORY (20041123C) O121800100019 (20041224A) Correction has been done. O121800100020 (20041228U) Last checking has been done. O121800100021 SAMPLE The deuterium gas target, pressurized to about 8 bar O121800100022 and cooled to liquid nitrogen temperature to increase O121800100023 its density consisted of an upright copper cylinder O121800100024 16-mm in diameter. The entrance and exit windows were O121800100025 covered by 12.7-mm thick HAVAR foil. The target was O121800100026 mounted directly beneath the liquid nitrogen reservoir O121800100027 which was contained in the lid of the chamber. O121800100028 ADD-RES (COMP) Faddeev calculations using various nucleon- O121800100029 nucleon potential models. O121800100030 DETECTOR (TELES,SCIN,SCIN) Scattered protons in beam polarimeterO121800100031 were detected in two del'ta E-E scintillator telescopesO121800100032 at 62.5-degree to the left and right of the beam. O121800100033 (SIBAR) Four with a active area of 20*50-mm**2 each O121800100034 were used to detect protons in secondary polarimeter. O121800100035 FACILITY (CYCLO,2SWTPSI).The Philips injector cyclotron. O121800100036 INC-SOURCE (POLIS) Atomic beam source. O121800100037 METHOD (DSCAT) A helium was used for beam and secondary O121800100038 polarimeters at high proton energies, resulting from O121800100039 primary laboratory scattering angles up to 80-degree. O121800100040 At larger scattering angles carbon polarimeter was O121800100041 used. O121800100042 (BCINT) Beam current measured in the Faraday cup was O121800100043 integrated and used to trigger a periodical reversal ofO121800100044 the beam polarization to reduce systematic errors. O121800100045 (EDE) O121800100046 ERR-ANALYS (ERR-S) The errors combine the statistical O121800100047 uncertainties of the raw signal and the background O121800100048 subtraction. O121800100049 The most significant systematic uncertainties are the O121800100050 following: O121800100051 (ERR-1) Accuracy of the primary scattering angle. O121800100052 (ERR-2) The analyzing powers of the secondary O121800100053 polarimeter were determined to an accuracy of 0.01. O121800100054 1. The error in the selection of the peak and O121800100055 background regions the authors estimated to be ~20% O121800100056 statistical error. O121800100057 3. A 2.5% relative normalization uncertainty common toO121800100058 all data is the uncertainty of the determination of theO121800100059 beam polarization O121800100060 other systematic uncertainties that were investigated O121800100061 and found to be negligible include: O121800100062 4. The uncertainty of the correction for the angular O121800100063 acceptance in primary scattering. O121800100064 5. The errors in the horizontal alignment of the O121800100065 quadrupole magnet triplet. O121800100066 CORRECTION The experimental results are corrected for the finite O121800100067 acceptance in the primary scattering and in the case O121800100068 of KX'Z for a small X-component of the beam O121800100069 polarization.
