Experimental site. 2213300100011 (2GERTUE) G.M., W.T. 2213300100012 FACILITY (ACCEL,2GERUEN) 2213300100013 INC-SOURCE (LAMB ) Erlangen Lamb-shift polarized ion source, 2213300100014 delivered 11.5 MeV vector polarized deuterons onto 2213300100015 a deuterium gas target. The target cell was 13 mm in 2213300100016 diameter by 50 mm thick, and filled to a pressure of 2213300100017 5 bar at a temperature of 77 K. The neutron polari- 2213300100018 zation was reversed every 50 sec. 2213300100019 (POLTR) Erlangen polarized proton target. It uses a 2213300100020 thin lanthanum magnesium nitrate (LMN), single crystal2213300100021 doped with 1% Nd at the La sites. The protons 2213300100022 of the crystal water molecules were polarized by 2213300100023 dynamic nuclear orientation at low temperatures, 1.3K,2213300100024 in a strong magnetic field, 1.85 T, using 70 GHz 2213300100025 microwaves. The LMN crystal had the shape of a slab, 2213300100026 300 micrometers thick and with a cross section area 2213300100027 of 6 by 6 mm. The distance from the center of the gas 2213300100028 cell to the LMN crystal was 10 cm. 2213300100029 (POLNS) polarized induced neutron source 2213300100030 METHOD (TOF ) Time-of-flight techniques was used to obtain 2213300100031 (COINC) coincidences between the proton and neutron 2213300100032 detectors. Coincidences between the Si-detectors of 2213300100033 the telescope were also recorded. 2213300100034 (PSD,EDE) The neutron detectors used PSD for neutron- 2213300100035 gamma discrimination. 2213300100036 DETECTOR (TELES,SOLST) A delta-E - E detector telescope, built 2213300100037 from two silicon barrier detectors, having an active 2213300100038 area of 12 mm in diameter and being 110 and 800 micro-2213300100039 meters thick, respectively, was used to detect the 2213300100040 recoil protons. The telescope was placed at an angle 2213300100041 of 45 degrees and at a distance of 6 cm from the LMN 2213300100042 crystal. 2213300100043 (SCIN ) A 10 cm diameter by 11.4 cm thick NE213 liquid 2213300100044 scintillation detector was used for neutron detection.2213300100045 The detector was placed at an angle of 45 degrees and 2213300100046 at a distance of 60 cm from the LMN cell. Two similar 2213300100047 detectors, one placed in the beam direction and the 2213300100048 other above the scattering plane served as fluence 2213300100049 monitors. The distance from the LMN cell to these 2213300100050 detectors were 3 m. 2213300100051 .The polarization of the deuteron beam was monitored 2213300100052 with a carbon polarimeter. 2213300100053 CORRECTION .The data were corrected for background by subtracting 2213300100054 the yield outside the time-of-flight peak. Corrections2213300100055 were also applied for dead-time and fluctuations in 2213300100056 the deuteron beam current. 2213300100057 ERR-ANALYS (DATA-ERR) One standard deviation. Includes counting 2213300100058 statistics and uncertainties in the neutron beam 2213300100059 polarization, the target polarization and the 2213300100060 analyzing power. 2213300100061 ANALYSIS .An analyzing power value of 0.019 +- 0.002 was assumed2213300100062 in the analysis. 2213300100063 STATUS (TABLE) .Tbl.2 from Nucl.Phys.
