O139100100025 HISTORY (20060423C) O139100100026 (20060506A) Correction. O139100100027 (20060529U) Last checking has been done. O139100100028 SAMPLE The deuterium cluster jet produced a target density of O139100100029 about 2.E+14 atoms/cm2 with a target length along the O139100100030 beam of 12-mm and a width of 4.9-mm. O139100100031 ADD-RES (COMP).The results are compared with a model taking O139100100032 into account one-nucleon exchange, single scattering O139100100033 and delta(1232) excitation in the intermediate state. O139100100034 DETECTOR (SPEC) The set of used detectors includes: O139100100035 (TELES,SIBAR,SIBAR,SIBAR) The silicon detector O139100100036 telescope to record recoils deuterons from small-angle O139100100037 elastic pd scattering. the detector provided an unambigO139100100038 Deutron identification with a detector resolution of O139100100039 300 KeV, O139100100040 and O139100100041 (TELES,MWPC,MWPC,MWPC,SCIN,SCIN) The telescope O139100100042 comprises a set of three multiwire proportional O139100100043 chambers and a two-plane scintillation hodoscope, O139100100044 consisting of vertically oriented counters (eight in O139100100045 first plane, nine in second). The detector was used to O139100100046 record a fast proton pair emitted in the forward O139100100047 direction with small excitation energy (< 3 MeV). O139100100048 INC-SOURCE (POLIS) O139100100049 FACILITY (SYNCH,2GERJUL) The ANKE-spectrometer at the internal O139100100050 beam of COSY-Julich with about 3.E+9 stored vertically O139100100051 polarized protons. O139100100052 METHOD (TOF) O139100100053 (INTB) O139100100054 (COINC) Recoil deuterons at angles around 90 degrees (IO139100100055 [L-system] were detected in first telescope in O139100100056 coincidence with elastically scatterd protons in secondO139100100057 telescope. O139100100058 COMMENT -By authors. The absence of azimuthal symmetry of the O139100100059 ANKE-spectrometer does not permit one to measure a O139100100060 vector analyzing power from the left-right count rate O139100100061 assymetry. The analyzing power was measured by O139100100062 reversing every two cycle the orientation of the O139100100063 polarization. O139100100064 ERR-ANALYS (ERR-S) Statistical uncertainty. O139100100065 (ERR-SYS) The systematic uncertainty of the analyzing O139100100066 power contains contributions from various sources, O139100100067 which were all added in quadrature.
