Mean values of the fission cross sections of 4064000100024 U-235 were used (see the continuous curve in D.Hughes, 4064000100025 etc. Neutron Cross Sections, New York, 1958.). 4064000100026 ERR-ANALYS Errors in the obtained values of radiation capture 4064000100027 cross sections of 1m neutrons were mainly determined 4064000100028 by errors in the fission cross sections of U-235, which4064000100029 were ~25% for En < 60 keV, ~12% for En = 60-150 keV, 4064000100030 ~8% for neutrons of higher energies (see REL-REF). 4064000100031 (ERR-S) Statistical error 4064000100032 STATUS (TABLE) Data from the author 4064000100033 (APRVD) Tolstikov, 1983.10 4064000100034 HISTORY (19831017C) Compiled at the centre. 4064000100035 (20050827U) Correction according to memo CP-E/70 4064000100036 Dates were corrected 4064000100037 (20160528A) SD:Updated to new date formats,lower case. 4064000100038 Title corrected following presentation in SJA,10,153; 4064000100039 year of the ref.
