This detector was 1454700100018 calibrated with a Physikalisch-Technische Bundestalt 1454700100019 152Eu standard source (assayed in 1976) using 1454700100020 the gamma-rays: 121.7, 344.3, 778.9, 964.0, 1085.8, 1454700100021 1112.1, 1408.0 keV. Its efficiency curve was extended 1454700100022 above 1400 to 2614 keV by counting a 232Th source 1454700100023 using the gamma-rays: 583.2, 763.3, 785.5, 860.5, 1454700100024 1620.7, 2614.5 keV. The relative peak efficiency 1454700100025 curve from the 232Th source was normalized to the 1454700100026 absolute curve from the 152Eu standard. From the 1454700100027 uncertainties in the peak areas and those of the 1454700100028 gamma-ray intensities, an uncertainty of +-5% between 1454700100029 121 and 1400 keV and +-8% from 1400 to 2614 keV was 1454700100030 assigned. 1454700100031 ADD-RES (G-SPC) Gamma-ray spectra of the spontaneously 1454700100032 fissioning actinides 244Cm and 252Cf. 1454700100033 HISTORY (20190827C) OG. 1454700100034 ENDBIB 32 0 1454700100035 NOCOMMON 0 0 1454700100036 ENDSUBENT 35 0 1454700199999 SUBENT 14547002 20190827 14571454700200001 BIB 6 28 1454700200002 REACTION (96-CM-244(0,F)ELEM/MASS,CUM,FY) 1454700200003 SAMPLE The 244Cm (approximately 6.109 Bq) is mixed in a 1454700200004 nickel powder matrix contained in doubly encapsulated 1454700200005 (nested) 304 stainless steel capsules with the outer 1454700200006 capsule dimension being 1.90-cm in diameter by 1454700200007 2.16-cm in length. 1454700200008 DECAY-DATA ((1.)38-SR-94,75.3SEC,DG,1427.7,0.942) 1454700200009 ((2.)43-TC-104,18.3MIN,DG,358.0,0.890) 1454700200010 ((3.)53-I-132,2.2956HR,DG,667.7,0.987) 1454700200011 ((4.)53-I-132,2.2956HR,DG,772.0,0.756) 1454700200012 ((5.)53-I-134,52.5MIN,DG,1072.6,0.149) 1454700200013 ((6.)53-I-134,52.5MIN,DG,1136.2,0.091) 1454700200014 ((7.)54-XE-135,9.HR,DG,249.8,0.900) 1454700200015 ((8.)54-XE-138,14.1MIN,DG,1768.3,0.167) 1454700200016 ((9.)55-CS-138,33.4MIN,DG,1009.0,0.298) 1454700200017 ((10.)55-CS-138,33.4MIN,DG,1435.8,0.763) 1454700200018 ((11.)55-CS-140,63.7SEC,DG,602.4,0.530) 1454700200019 ((12.)56-BA-140,12.752D,DG,537.0,0.244) 1454700200020 ((13.)57-LA-140,1.678D,DG,487.0,0.455) 1454700200021 ((14.)57-LA-140,1.678D,DG,1596.2,0.954) 1454700200022 ((15.)57-LA-144,40.8SEC,DG,397.4,0.943) 1454700200023 ERR-ANALYS No information on uncertainties 1454700200024 STATUS (TABLE) Table 2 in the main ref.
