F014200100003 AUTHOR (R.L.Wolfgang,W.F.Libby) F014200100004 INSTITUTE (1USACHI) F014200100005 REFERENCE (J,PR,85,437,1952) F014200100006 SAMPLE For the 2- to 8-MeV deuteron energy range pieces of F014200100007 1.4-mil rolled beryllium foil were used as a target. F014200100008 This foil was sandwiched between five 4-mil F014200100009 thicknesses of aluminum backing and another of aluminumF014200100010 foils which was used to slow the beam to the desired F014200100011 energy. This sandwich was then covered by a 'hut' of F014200100012 three 4-mil thicknesses of aluminum foil. F014200100013 FACILITY (CYCLO,1USACHI) The 37-inch 8-Mev cyclotron and F014200100014 (CCW,1USACHI) the 400-kev Cockroft-Walton accelerator F014200100015 supplied the deuterons. F014200100016 DETECTOR (GEMUC) Self-quenching G-M counters containing argon, F014200100017 alcohol, and up to two centimeters of hydrogen have F014200100018 been used. F014200100019 METHOD After a bombardment was completed, the beryllium and F014200100020 all the aluminum foils were placed in a alumina cup in F014200100021 porcelain furnace tube in a hydrogen atmosphere. This F014200100022 tube was heated for thirty minutes to 950 to 1000 F014200100023 degr. After cooling to about 350 degr., the hydrogen, F014200100024 now containing the tritium, was pumped into a counter F014200100025 already containing 1.8 cm ethylene and 6 cm argon and F014200100026 was counted. F014200100027 ERR-ANALYS (DATA-ERR) Counting errors and local variations in F014200100028 thickness of the thin berryllium foils contributed to F014200100029 the errors in the individual mean cross-section F014200100030 determination. F014200100031 HISTORY (19840604C) F014200100032 (19990407A) CNPD: corrected 4-dig. year F014200100033 (20130625A) AUTHOR, REFERENCE, FACILITY, SAMPLE, F014200100034 DETECTOR were corrected. METHOD was introduced. ERR-T F014200100035 was replaced with DATA-ERR. REACTION record was F014200100036 corrected. In sub 002 data presentation was changed F014200100037 according to the table from the article.
