The cross sections for the 3175100100019 89.9- and 221.2-keV secondary gamma-rays in 152Eu and 3175100100020 the 68.2-keV gamma-ray in 154Eu were measured 3175100100021 relative to the 6.51 +/- 0.30 cross for the 1951-keV 3175100100022 from the 35Cl(n,g)36Cl reaction . All other gamma-ray 3175100100023 cross sections were obtained relative to these 3175100100024 standardized cross sections. 3175100100025 METHOD (GSPEC) 3175100100026 (STATD) The thermal cross section was determined as 3175100100027 a sum of observed gamma-ray cross sections populating 3175100100028 the ground state and estimated unobserved intensities 3175100100029 based on statistical calculations using DICEBOX Monte 3175100100030 Carlo code. 3175100100031 ERR-ANALYS (DATA-ERR) No information on uncertainty analysis. 3175100100032 STATUS (TABLE) Data from Table 1 of NDS,119,88,2014. 3175100100033 (PRELM) 3175100100034 HISTORY (20150331C) VS, 3175100100035 ENDBIB 33 0 3175100100036 COMMON 4 3 3175100100037 EN E-NRM MONIT MONIT-ERR 3175100100038 EV KEV B B 3175100100039 0.0253 1951. 6.51 0.30 3175100100040 ENDCOMMON 3 0 3175100100041 ENDSUBENT 40 0 3175100199999 SUBENT 31751002 20150331 31693175100200001 BIB 3 5 3175100200002 REACTION (63-EU-151(N,G)63-EU-152-G,,SIG,,,DERIV) 3175100200003 Derived from the measured prompt gamma-ray production 3175100200004 cross sections and calculated above the E(crit) 3175100200005 SAMPLE (63-EU-151,ENR=0.92) powdered Eu2O3 sample 3175100200006 CORRECTION Effective g-factor 1.377 +/- 0.004 3175100200007 ENDBIB 5 0 3175100200008 NOCOMMON 0 0 3175100200009 DATA 3 1 3175100200010 DATA DATA-ERR LVL-FIN 3175100200011 B B MEV 3175100200012 7060. 400. 0. 3175100200013 ENDDATA 3 0 3175100200014 ENDSUBENT 13 0 3175100299999 SUBENT 31751003 20150331 31693175100300001 BIB 3 5 3175100300002 REACTION (63-EU-151(N,G)63-EU-152-M1,,SIG,,,DERIV) 3175100300003 SAMPLE (63-EU-151,ENR=0.92) powdered Eu2O3 sample 3175100300004 CORRECTION Effective g-factor 1.377 +/- 0.004 3175100300005 Derived from the measured prompt gamma-ray production 3175100300006 cross sections and calculated above the E(crit) 3175100300007 ENDBIB 5 0 3175100300008 NOCOMMON 0 0 3175100300009 DATA 3 1 3175100300010 DATA DATA-ERR LVL-FIN 3175100300011 B B KEV 3175100300012 2345. 220. 46. 3175100300013 ENDDATA 3 0 3175100300014 ENDSUBENT 13 0 3175100399999 SUBENT 31751004 20150331 31693175100400001 BIB 3 6 3175100400002 REACTION (63-EU-151(N,G)63-EU-152,,SIG,,,DERIV) 3175100400003 Sum of 151Eu(n,gamma)152m1Eu and 3175100400004 151Eu(n,gamma)152gEu cross sections 3175100400005 SAMPLE (63-EU-151,ENR=0.92) powdered Eu2O3 sample 3175100400006 STATUS (DEP,31753002) 151Eu(n,gamma)152gEu cross section 3175100400007 (DEP,31753003) 151Eu(n,gamma)152m1Eu cross section 3175100400008 ENDBIB 6 0 3175100400009 NOCOMMON 0 0 3175100400010 DATA 2 1 3175100400011 DATA DATA-ERR 3175100400012 B B 3175100400013 9405. 460. 3175100400014 ENDDATA 3 0 3175100400015 ENDSUBENT 14 0 3175100499999 SUBENT 31751005 20150331 31693175100500001 BIB 3 3 3175100500002 REACTION (63-EU-153(N,G)63-EU-154,,SIG) 3175100500003 SAMPLE (63-EU-153,ENR=0.985) powdered Eu2O3 sample 3175100500004 CORRECTION Effective g-factor 1.026 +/- 0.004 3175100500005 ENDBIB 3 0 3175100500006 NOCOMMON 0 0 3175100500007 DATA 2 1 3175100500008 DATA DATA-ERR 3175100500009 B B 3175100500010 335. 10. 3175100500011 ENDDATA 3 0 3175100500012 ENDSUBENT 11 0 3175100599999 ENDENTRY 5 0 3175199999999
