B007800100010 FACILITY (SYNCH,1USABNL) Cosmotron B007800100011 METHOD (INTB,CHSEP,SITA,MOSEP) B007800100012 after dissolution of the target foils in 1.8 to 2.5 minB007800100013 after the end of irradiation Ne-24 was separated from B007800100014 Na-24 within 20 sec. After Ne-24 had decayed to Na-24 B007800100015 this nuclide was used in the different fractions eitherB007800100016 for the determination of the cumulative production of B007800100017 Ne-24 or the independent production of Na-24. B007800100018 SAMPLE Targets consisted of three 0.001 inch Al-foils and B007800100019 three 0.001 to 0.003 inch foils of the specified B007800100020 metal. The middle foils were used for monitoring and B007800100021 to determine Na-24 and Ne-24, respectively. B007800100022 MONITOR (13-AL-27(P,X)11-NA-24,CUM,SIG,,,EVAL) B007800100023 MONIT-REF (B0022003,J.B.Cumming,J,ARN,13,261,1963) B007800100024 DETECTOR (NAICR) B007800100025 used when sufficient Na-24 activity was present B007800100026 (PROPC) B007800100027 used at lower Na-24 activities. a few samples with B007800100028 very low counting rates were measured on low-level B007800100029 beta counters. B007800100030 COMMENT In approximately half the experiments the cumulative B007800100031 yield of Na-24 was measured also in one of the B007800100032 remaining foils. These cross sections agreed to +-15% B007800100033 with those of the sums of cumulative Ne-24 plus B007800100034 independent Na-24. B007800100035 Additional external irradiations of Cu and Ag targets B007800100036 at 3 GeV using a continuous flow system to collect the B007800100037 Ne-24 produced during the irradiation yielded values B007800100038 which agreed within +-10% with those obtained from B007800100039 internal irradiations. Thus No appreciable amount of B007800100040 Ne-24 compared to Na-24 was lost during the internal B007800100041 irradiations as a result of target heating. B007800100042 In general two independent experiments were performed B007800100043 for determination of the cross section ratios. Four B007800100044 experiments were made for Ag and U with 1 GeV protons B007800100045 and three experiments for Au with 3 GeV protons. B007800100046 ERR-ANALYS (DATA-ERR) The ratio-errors given are the mean B007800100047 deviations of several runs or 10% if the mean deviationB007800100048 is smaller than this figure as stated by the author.
