Incident neutrons were 2225000100014 transversely polarized (70% at En=1 eV) upon 2225000100015 transmission through filter. The neutron polarization 2225000100016 was determined by measuring the neutron transmittance 2225000100017 of the filter. The neutron spin was reversed every 2225000100018 4 sec by reversing the magnetic field. The neutron 2225000100019 beam was collimated to 1.8 cm diam. The intensity was 2225000100020 monitored by counting the capture gamma-rays from an 2225000100021 annular indium foil. The neutron energy was determined2225000100022 by TOF technique. 2225000100023 SAMPLE La-139 target was a metal column 2.5 cm in diam. 2225000100024 and 3 cm in height. As the bromine target, carbon 2225000100025 tetrabromide of the same size was used. All Cd-111, 2225000100026 Nb-93, Pd-108 and Sn-124 targets were metal disks with2225000100027 thickness 1.15,2.5,0.7 and 3 cm respectively. 2225000100028 DETECTOR (SCIN) For the 1st type of measurements (see method) 2225000100029 3 sets of BaF2 gamma-ray counters were used 2225000100030 covering 85% of 4pi steradians. 2225000100031 B4C was used to absorb neutrons scattered from target.2225000100032 In the 2nd and 3rd types of measurements, BGO scin. 2225000100033 crystals were used. 2225000100034 In all measurements, the neutron energy spectrum was 2225000100035 measured using a B-10 loaded liquid scin. placed at 2225000100036 9.4 m from the neutron source (0 degree angle) 2225000100037 ERR-ANALYS (DATA-ERR) No information 2225000100038 STATUS (TABLE) Table 1 from Nucl.Phys.A552(1993)293 2225000100039 HISTORY (19930817C) N.O. 2225000100040 (20181221A) SD:Updated to new date formats,lower case. 2225000100041 Facility code added.
