O064000100012 (R,,H.A.TEWES+,J,PR,88,860,1952) O064000100013 (R,,FOWLER+,J,PR,86,71,1952) O064000100014 Data on Relative Fission Yields were Taken from the O064000100015 Two Above Mentioned Ref'S and from Private O064000100016 Communications of Jones+ and Timnick+. O064000100017 FACILITY (CYCLO,1USAORL) O064000100018 SAMPLE Stacks of Natural Uranium Metal, Thorium Metal, and U- O064000100019 235-Oxide Plated on Platinum. O064000100020 METHOD (INTB,STTA,EDEG,ACTIV,MOSEP) The Energy of the O064000100021 Incident Protons was 21.9 MeV. The Stopping Powers of O064000100022 Uranium and Thorium were Determined Experimentally O064000100023 Relative to That of Copper. O064000100024 (RCHEM,BSPEC) The Fission Product Used Most O064000100025 Consistently was Zr-97. Several Checks were Made with O064000100026 Ba-139 and Sr-91.

O064000100032 COMMENT -By Authors- As a Check of the Beam Monitoring Method, O064000100033 The Cross Section of the Reaction 12-Mg-0(P,X)11-Na-22 O064000100034 Was Measured Near 20 MeV. It was Found by 20% Higher O064000100035 Than the Result of Batzel+, See Rel-Ref. To Take this O064000100036 Discrepancy Into Account, the Measured Fission Cross O064000100037 Sections were Reduced by 10%. O064000100038 -By Compiler- The Discrepancy Mentioned by Authors O064000100039 Originates Most Likely from the Defect in the O064000100040 Monitoring Data, Mentioned by Hille+ - See Rel-Ref - O064000100041 The Monitor Reaction Data of Ghoshal+ are Shifted O064000100042 Systematically Towards Higher Energies by 1-1.5 MeV, O064000100043 Probably Due to the Old Stopping-Power Values Used to O064000100044 Calculate the Energy Loss in the Foils.
