The 3304800100011 resolution of the detector was 1.8 keV for the 1332 3304800100012 keV peak of 60Co. 3304800100013 METHOD (REC,RCHEM) 106Ru was used as tracer for chemical 3304800100014 yield determination. 3304800100015 ERR-ANALYS (DATA-ERR) The overall error on measured yield values 3304800100016 is 5-7%. The uncertainties shown on the cumulative 3304800100017 yields are the standard deviations on the average of 3304800100018 total number of determinations. The uncertainties 3304800100019 considered include detector efficiency, chemical yield 3304800100020 and counting statistics. The error on the half-life 3304800100021 and gamma ray abundances were not taken into account. 3304800100022 HISTORY (20140501C) Compiled by R.Ghosh, B.Jyrwa, NEHU, 3304800100023 Shillong, Meghalaya, India 3304800100024 ENDBIB 22 0 3304800100025 NOCOMMON 0 0 3304800100026 ENDSUBENT 25 0 3304800199999 SUBENT 33048002 20140501 31643304800200001 BIB 5 11 3304800200002 REACTION (98-CF-252(0,F)ELEM/MASS,CUM,FY) 3304800200003 DECAY-DATA ((1.)44-RU-105,4.4HR,DG,725.,0.445) 3304800200004 ((2.)44-RU-107,3.8MIN,DG,194.,0.143) 3304800200005 ((3.)44-RU-108,4.5MIN,DG,165.,0.320) 3304800200006 ((4.)44-RU-109,34.5SEC,DG,206.,0.330) 3304800200007 MONITOR (98-CF-252(0,F)43-TC-104,CUM,FY) The yield of 104Tc was3304800200008 taken from Technical Journal, Turkish Atomic Energy 3304800200009 Commission,7(1980)8, L.Toppare et. al. 3304800200010 DECAY-MON (43-TC-104,,DG,358.) 3304800200011 STATUS (TABLE) Table 2 of Journal of Radioanalytical and 3304800200012 Nuclear Chemistry,82,(1984)263. 3304800200013 ENDBIB 11 0 3304800200014 COMMON 1 3 3304800200015 MONIT 3304800200016 PC/FIS 3304800200017 5.5 3304800200018 ENDCOMMON 3 0 3304800200019 DATA 5 4 3304800200020 ELEMENT MASS DATA DATA-ERR DECAY-FLAG 3304800200021 NO-DIM NO-DIM PC/FIS PC/FIS NO-DIM 3304800200022 44. 105. 7.20 0.30 1. 3304800200023 44. 107. 6.35 0.33 2. 3304800200024 44. 108. 5.89 0.29 3. 3304800200025 44. 109. 4.08 0.30 4. 3304800200026 ENDDATA 6 0 3304800200027 ENDSUBENT 26 0 3304800299999 SUBENT 33048003 20140501 31643304800300001 BIB 3 6 3304800300002 REACTION (98-CF-252(0,F)MASS,CHN,FY) 3304800300003 STATUS (TABLE) Table 3 of Journal of Radioanalytical and 3304800300004 Nuclear Chemistry,82,(1984)263. 3304800300005 (DEP,33048002) Cumulative yield given. 3304800300006 ANALYSIS Using fractional cumulative yield obtained from 3304800300007 Wahl's prescription with most probable charge of 0.59 3304800300008 ENDBIB 6 0 3304800300009 NOCOMMON 0 0 3304800300010 DATA 3 4 3304800300011 MASS DATA DATA-ERR 3304800300012 NO-DIM PC/FIS PC/FIS 3304800300013 105. 7.20 0.30 3304800300014 107. 6.38 0.33 3304800300015 108. 6.21 0.31 3304800300016 109. 5.00 0.37 3304800300017 ENDDATA 6 0 3304800300018 ENDSUBENT 17 0 3304800399999 ENDENTRY 3 0 3304899999999
