The mass 2157200100011 analysis for the Am material was - 99.969% wt for 2157200100012 Am-243, 0.031% wt for Am-241 and less than 0.00003% wt2157200100013 for Am-242 and Am-244. 2157200100014 METHOD The fission fragments were recorded with a Multi-8 2157200100015 data recording system. 2157200100016 DETECTOR (SIBAR) Fission fragments were detected by two 2157200100017 surface barrier detectors. 2157200100018 ANALYSIS 70000 fissions per day for Am-243 targets. The Am-243 2157200100019 Maxwellian cross section was calculated by 2157200100020 comparison of the corresponding fission events of 2157200100021 Am-243 and natural uranium targets. 2157200100022 MONITOR (92-U-235(N,F),,SIG,,MXW) 2157200100023 CORRECTION A correction for about 0.5% was applied 2157200100024 for the Am-241 contribution. 2157200100025 ERR-ANALYS (DATA-ERR) The error given is composed of the 2157200100026 uncertainties in the weights of the materials and 2157200100027 the fission cross section of U-235. 2157200100028 STATUS (TABLE) Taken from Annals of Nuclear Energy 6(1979)561.2157200100029 HISTORY (19800509C) 2157200100030 (20160725A) SD:Updated to new date formats,lower case. 2157200100031 Author's name corrected ( M.Agshar -> M.Asghar). 2157200100032 BIB update. 2157200100033 ENDBIB 31 0 2157200100034 COMMON 3 3 2157200100035 EN-NRM MONIT MONIT-ERR 2157200100036 EV B B 2157200100037 2.5300E-02 582.2 1.3 2157200100038 ENDCOMMON 3 0 2157200100039 ENDSUBENT 38 0 2157200199999 SUBENT 21572002 20160725 22522157200200001 BIB 3 6 2157200200002 REACTION (95-AM-243(N,F),,SIG,,MXW) 2157200200003 INC-SPECT Cold neutron beam with Maxwellian energy distribution 2157200200004 at 25 K.
