The foils were supported by 1.0 mm 2004800100017 thick aluminium disks. 2004800100018 METHOD (ACTIV) Activation 2004800100019 cadmium ratio measurement of thin foils in a2004800100020 neutron beam. Comparison was made with a 1/V detector 2004800100021 and the neutron spectra were measured with a chopper. 2004800100022 MONITOR (79-AU-197(N,G)79-AU-198,,SIG) 2004800100023 MONIT-REF (,D.J.Hughes+,R,BNL-325,1958) 2004800100024 COMMENT Resonance integrals also estimated from the resonance 2004800100025 parameter data of BNL-325, computed value of 2004800100026 resonance integral = 1529 +- 70 barns. 2004800100027 STATUS (TABLE) Data from p.106 of J.Nucl.En.,A11(1960)101 2004800100028 CORRECTION The main correction depends on deviation from the 1/v 2004800100029 law of the absorption cross-section in the thermal 2004800100030 region 2004800100031 Self-absorption correction of 4 barns 2004800100032 ERR-ANALYS (DATA-ERR) No information given 2004800100033 HISTORY (19710503T) From NEUDADA file 2004800100034 (20190131U) SD:Updated to new date formats,lower case. 2004800100035 MONIT-REF, COMMON section added. 2004800100036 ENDBIB 34 0 2004800100037 COMMON 3 3 2004800100038 EN-NRM MONIT MONIT-ERR 2004800100039 EV B B 2004800100040 0.0253 98.8 0.3 2004800100041 ENDCOMMON 3 0 2004800100042 ENDSUBENT 41 0 2004800199999 SUBENT 20048002 20190131 22742004800200001 BIB 2 2 2004800200002 REACTION (79-AU-197(N,G)79-AU-198,,RI) 2004800200003 PART-DET (B-,DG) Decay beta- electrons and decay gammas. 2004800200004 ENDBIB 2 0 2004800200005 NOCOMMON 0 0 2004800200006 DATA 3 1 2004800200007 EN-MIN DATA DATA-ERR 2004800200008 MEV B B 2004800200009 5.0E-07 1490. 40. 2004800200010 ENDDATA 3 0 2004800200011 ENDSUBENT 10 0 2004800299999 ENDENTRY 2 0 2004899999999
