External-beam 1383400100007 facility employed. 1383400100008 INC-SOURCE (THCOL) Highly collimated external beam of thermal 1383400100009 neutrons, (height ~2 cm, width ~0.5 cm, thermal flux 1383400100010 ~5E7 neutrons/cm2/s) effectively free of fast 1383400100011 neutrons and pile gamma rays, extracted from a 1383400100012 modified thermal-column at the CP-5 reactor. 1383400100013 INC-SPECT Thermal spectrum (cadmium ratio ~570). 1383400100014 SAMPLE Targets consisted of pressed cylindrical pellets of 1383400100015 of WO3 enriched to 97.2% in 186W and contained in 1383400100016 thin-walled (4.5 mg/cm2) aluminum holders. 1383400100017 DETECTOR (GELI) Two coaxially drifted Ge(Li) detectors (active 1383400100018 volumes ~20 and ~30 cm3) mounted at 180 deg to 1383400100019 each other and positioned 2.5 cm from the beam axis. 1383400100020 Energy resolution of both detectors ~2.7 keV at 1.33 1383400100021 MeV. The detectors shielded from scattered neutrons by1383400100022 thin (0.25 cm thick) 6LiF disks. 1383400100023 METHOD Study of the primary and secondary transitions in W187 1383400100024 USING singles and coincidence gamma-ray techniques. 1383400100025 MONITOR Intensities relative to intensity of 145.7-keV 1383400100026 transition, taken as 100. 1383400100027 ERR-ANALYS (E-ERR) Uncertainties in gamma-ray energies. 1383400100028 (DATA-ERR1) Upper limit of the uncertainties in line 1383400100029 intensities. 1383400100030 (DATA-ERR2) Lower limit of the uncertainties in line 1383400100031
