Thermal neutron 2227200100013 captures were discriminated by time-of-flight. 2227200100014 SAMPLE Standard Au sample (5.5 cm in diam., 0.17 cm in thick).2227200100015 Li, Au and blank runs were done cyclically. 2227200100016 (3-LI-6,ENR=0.9248) Metallic Li (60 mm diam.x 26 mm) 2227200100017 packed in a thin vinyl film. The isotopic abundance 2227200100018 was investigated by mass spectrometry. 2227200100019 METHOD (TOF,PHD,PHWT) 2227200100020 DETECTOR (NAICR) 7.6 cm (diam.) and 15.2 cm thick NaI(Tl) 2227200100021 detector surrounded by 25.4 cm (diam.) and 28.0 cm 2227200100022 thick annular NaI(Tl) detector. Set at 125 deg with 2227200100023 respect to the proton beam direction. 2227200100024 (GLASD) 6Li glass time-of-flight detector set at 2227200100025 14 deg with respect to the proton beam. 2227200100026 CORRECTION Corrected for 2227200100027 - gamma-ray absorption in the sample 2227200100028 - sample position dependence of gamma-ray detection 2227200100029 efficiency 2227200100030 - Neutron self-shielding and multiple scattering 2227200100031 HISTORY (19940115C) N.O. 2227200100032 (19950420E) 2227200100033 (19961022D) Entry deleted due to the data repetition 2227200100034 in ENTRY 22271, SAN 002 - 004.
