1469000100004 AUTHOR (E.Fermi,L.Marshall) 1469000100005 REFERENCE (J,PR,72,408,1947) 1469000100006 #doi:10.1103/PhysRev.72.408 1469000100007 INSTITUTE (1USAANL,1USACHI) 1469000100008 FACILITY (REAC,1USAANL) The Argonne heavy water pile. 1469000100009 INC-SPECT A beam of neutrons from the thermal column of the 1469000100010 Argonne heavy water pile was passed through a BeO 1469000100011 filter (100 g/cm2) or a graphite filter (57 g/cm2). 1469000100012 METHOD (TRN) In this beam of filtered neutrons the 1469000100013 transmissions of the various elements were measured 1469000100014 and cross sections deduced. 1469000100015 COMMENT Compiler's comment: Unfiltered neutrons of 1.8 A 1469000100016 correspond to 0.02523 eV, essentially, thermal neutron 1469000100017 spectrum.
