The above process was repeated 100 times at 2177000100013 intervals of 18 seconds. Finally, the Na-24-m activity 2177000100014 from the monitor reaction was measured for 3600 seconds2177000100015 (ASSOP) Fluctuations in the neutron flux were 2177000100016 monitored by counting the associated alpha particles 2177000100017 from the D-T reaction. 2177000100018 The values reported are those averaged from three or 2177000100019 four separate runs. 2177000100020 DETECTOR (GELI) Coaxial 55 cm3 Ge(Li) detector for decay gammas 2177000100021 (SIBAR) silicon surface barrier detector for alphas. 2177000100022 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) 2177000100023 MONIT-REF (,J.C.Robertson+,J,JNE,27,139,1973) 2177000100024 REL-REF (I,,S.Amemiya+,J,NST,11,395,1974) - The details of the 2177000100025 irradiation and counting system 2177000100026 PART-DET (DG) 2177000100027 ERR-ANALYS (DATA-ERR) Includes contributions from uncertainties 2177000100028 (ERR-1) uncertainty in detection efficiencies, 2177000100029 (MONIT-ERR) uncertainty in monitor cross section, 2177000100030 * and counting statistics. 2177000100031 It does not include errors in the half-life and in the 2177000100032 abundance of each gamma energy per decay. 2177000100033 STATUS (TABLE) .Data taken from Tbl.2 of NST,18,323. 2177000100034 HISTORY (19820218C) A.P.T. 2177000100035 (19840106U) A.P.T.
