The neutron 3278500100012 production target was a tritium-titanium target 2.20 3278500100013 mg/cm2 in thickness. 3278500100014 SAMPLE (75-RE-185,NAT=0.3740) Disk of natural rhenium metal 3278500100015 (purity 99.99%, about 1.0 mm in thickness, 2.0 cm in 3278500100016 diameter, China New Metal Materials Technology Co, 3278500100017 Ltd.) was sandwiched between disks of niobium (purity 3278500100018 99.99%, 0.12 mm in thickness) of the same diameter. 3278500100019 Three such samples (Nb-Re-Nb) were prepared for 3278500100020 irradiation. The thicknesses were 0.0984, 0.0973, and 3278500100021 0.0939 cm. 3278500100022 METHOD (ACTIV) The neutron yield was 3 to 4E10 n/4pi/s. 3278500100023 Groups of samples were placed at 0, 90 or 135 deg 3278500100024 with respect to the beam line and centered about the 3278500100025 T-Ti target at distances of about 40 mm. 3278500100026 DETECTOR (HPGE) The detector was about 68% relative 3278500100027 efficiency, and 1.69 keV resolution at 1332.5 keV of 3278500100028 60Co. The detector was connected to a digital gamma 3278500100029 spectrometry system (ORTEC, model GEM 60P) and 3278500100030 Maestro data acquisition software. The separation 3278500100031 between sample and detector was variable within a 3278500100032 range of 0 to 8 cm. 3278500100033 MONITOR (41-NB-93(N,2N)41-NB-92-M,,SIG) 3278500100034 DECAY-MON (41-NB-92-M,10.15D,DG,934.44,0.9915) 3278500100035 MONIT-REF (,M.Wagner+,B,PH-DAT,13-5,,1990) 3278500100036 ERR-ANALYS (ERR-T) Total uncertainty 3278500100037 (ERR-1,2.,3.)
