The powdered samples were put 3166900100013 in thin plastic packets. 3166900100014 METHOD (ACTIV,GSPEC) The activation method and the absolute - 3166900100015 gamma-counting technique were used to determine the 3166900100016 isomeric cross-section ratios. 3166900100017 DETECTOR (HPGE) HPGe-detector (ORTEC GEM 20190) with volume 3166900100018 100 cm3 and energy resolulion 1.8 keV for the line 3166900100019 Egamma - 1332 keV of 60Co 3166900100020 ERR-ANALYS (DATA-ERR) Nothing said about errors 3166900100021 CORRECTION The errors associated with neutron fluxes and the 3166900100022 geometry of exposures and measurements were eliminated 3166900100023 in determining isomeric ratios, because the isomeric 3166900100024 and ground states were obtained in the same exposure 3166900100025 run and the required quantities (yields or cross- 3166900100026 sections) were measured for them under identical 3166900100027 conditions. 3166900100028 STATUS (TABLE) Tbl.2 from the article 3166900100029 HISTORY (20090213C) SD 3166900100030 ENDBIB 28 0 3166900100031 COMMON 1 3 3166900100032 EN 3166900100033 EV 3166900100034 0.0253 3166900100035 ENDCOMMON 3 0 3166900100036 ENDSUBENT 35 0 3166900199999 SUBENT 31669002 20090213 31363166900200001 BIB 3 6 3166900200002 REACTION 1(27-CO-59(N,G)27-CO-60-M/G,,SIG/RAT) 3166900200003 2(27-CO-59(N,G)27-CO-60-M/T,,SIG/RAT) 3166900200004 DECAY-DATA (27-CO-60-M,10.47MIN,DG,58.6,0.0203,DG,1332.5,0.0025) 3166900200005 (27-CO-60-G,5.27YR,DG,1173.2,0.999,DG,1332.5,1.) 3166900200006 LEVEL-PROP (27-CO-60-G,E-LVL=0.,SPIN=5.,PARITY=+1.) 3166900200007 (27-CO-60-M,E-LVL=58.6,SPIN=2.,PARITY=+1.) 3166900200008 ENDBIB 6 0 3166900200009 NOCOMMON 0 0 3166900200010 DATA 4 1 3166900200011 DATA 1DATA-ERR 1DATA 2DATA-ERR 2 3166900200012 NO-DIM NO-DIM NO-DIM NO-DIM 3166900200013 0.96 0.15 0.49 0.08 3166900200014 ENDDATA 3 0 3166900200015 ENDSUBENT 14 0 3166900299999 SUBENT 31669003 20090213 31363166900300001 BIB 3 7 3166900300002 REACTION 1(45-RH-103(N,G)45-RH-104-M/G,,SIG/RAT) 3166900300003 2(45-RH-103(N,G)45-RH-104-M/T,,SIG/RAT) 3166900300004 DECAY-DATA (45-RH-104-M,4.34MIN,DG,51.4,0.482,DG,77.5,0.0207, 3166900300005 DG,97.1,0.0299) 3166900300006 (45-RH-104-G,42.3SEC,DG,555.8,0.0199) 3166900300007 LEVEL-PROP (45-RH-104-G,E-LVL=0.,SPIN=1.,PARITY=+1.) 3166900300008 (45-RH-104-M,E-LVL=51.4,SPIN=5.,PARITY=+1.) 3166900300009 ENDBIB 7 0 3166900300010 NOCOMMON 0 0 3166900300011 DATA 4 1 3166900300012 DATA 1DATA-ERR 1DATA 2DATA-ERR 2 3166900300013 NO-DIM NO-DIM NO-DIM NO-DIM 3166900300014 0.08 0.005 0.074 0.011 3166900300015 ENDDATA 3 0 3166900300016 ENDSUBENT 15 0 3166900399999 ENDENTRY 3 0 3166999999999
