Ratios between vanadium and hydrogen count 1437300100028 rates scattering and absorption were formed, from 1437300100029 which cross section ratio absorption/scattering can 1437300100030 be deduced for each element separately. 1437300100031 ERR-ANALYS (DATA-ERR) No information given 1437300100032 HISTORY (20130920C) Compiled by S.H. 1437300100033 ENDBIB 31 0 1437300100034 COMMON 2 3 1437300100035 EN EN-NRM 1437300100036 NANO-EV EV 1437300100037 80.0 0.0253 1437300100038 ENDCOMMON 3 0 1437300100039 ENDSUBENT 38 0 1437300199999 SUBENT 14373002 20130920 13951437300200001 BIB 5 7 1437300200002 REACTION (1-H-1(N,THS)1-H-1,,SIG) Total scattering cs 1437300200003 STATUS (TABLE) Data taken from tab. 1 of the reference 1437300200004 MONITOR (1-H-1(N,G)1-H-2,,SIG) 1437300200005 It is assumed that cross section follow 1/v law 1437300200006 between 4 m/s and 2200 m/s velocities 1437300200007 MONIT-REF (V1001002,S.F.Mughabghab,B,NEUT.RES,,2006) 1437300200008 SAMPLE Polyethylene target with thickness of 1.6 mm 1437300200009 ENDBIB 7 0 1437300200010 NOCOMMON 0 0 1437300200011 DATA 4 1 1437300200012 DATA DATA-ERR MONIT MONIT-ERR 1437300200013 B B B B 1437300200014 25.0 9.0 0.3326 0.0007 1437300200015 ENDDATA 3 0 1437300200016 ENDSUBENT 15 0 1437300299999 SUBENT 14373003 20130920 13951437300300001 BIB 5 7 1437300300002 REACTION (23-V-0(N,THS)23-V-0,,SIG) Total scattering cs 1437300300003 STATUS (TABLE) Data taken from tab. 1 of the reference 1437300300004 MONITOR (23-V-0(N,G),,SIG) 1437300300005 It is assumed that cross section follow 1/v law 1437300300006 between 4 m/s and 2200 m/s velocities 1437300300007 MONIT-REF (V1001175,S.F.Mughabghab,B,NEUT.RES,,2006) 1437300300008 SAMPLE Vanadium sample with thickness of 0.25 mm 1437300300009 ENDBIB 7 0 1437300300010 NOCOMMON 0 0 1437300300011 DATA 4 1 1437300300012 DATA DATA-ERR MONIT MONIT-ERR 1437300300013 B B B B 1437300300014 2062.0 135.0 4.92 0.05 1437300300015 ENDDATA 3 0 1437300300016 ENDSUBENT 15 0 1437300399999 ENDENTRY 3 0 1437399999999
