B015200100003 Se-73 B015200100004 AUTHOR (M.GUILLAUME, R.M.LAMBRECHT, A.P.WOLF) B015200100005 INSTITUTE (1USABNL).Chemistry Department B015200100006 REFERENCE (J,ARI,29,411,1978) B015200100007 FACILITY (ISOCY,1USABNL) B015200100008 METHOD (STTA,EDEG,MOSEP,BCINT,EXTB) B015200100009 A Highly Defocussed, Diffused and Collimated Beam was B015200100010 Used. The Typical Irradiation Condition was B015200100011 1 Microampere For 300 Sec. Energy Degradation was B015200100012 Calculated According to C.F.Williamson Et Al., B015200100013 Cea-3042(1966). B015200100014 DETECTOR (GELI) B015200100015 ERR-ANALYS (ERR-T) The Counting Error at the 95.5% Confidence B015200100016 Level was Less Than 3%. The Greatest Errors Arise from B015200100017 The Uncertainties in the Irradiation Parameters B015200100018 Resulting from any Lack of Uniformity in the Germanium B015200100019 Thickness (< 2%), and Specifically from Heterogeneous B015200100020 Distribution, If any. B015200100021 Impurities Present in the Target Other Than Ge were B015200100022 Smaller Than 1%. B015200100023 Recoil Losses from the Polystyrene Matrix were Very B015200100024 Small and were Neglected in Computing the Cross B015200100025 Sections. Overall Errors are Typically of the Order of B015200100026 14%. The Uncertainty in the Incident Particle Beam B015200100027 Energy was Estimated As 1%. B015200100028 ADD-RES The Production of Se-73 For Radiotracer Studies was B015200100029 Investigated with He-3 and He-4 Activation. An Optimum B015200100030 Thick Target Production Rate of 933 Micro-Ci/Micro-Ahr B015200100031 (RADIONUCLIDIC PURITY > 99.99%) Was Found Using the B015200100032 Ge-72(HE-3,2N)Se-73 Reaction on Isotopically Enriched B015200100033 Ge-72 with He-3 Degraded from 37 MeV to 18 MeV on a 151B015200100034 Mg/Cm**2 Target of Ge-Dioxide. Thin Target Production B015200100035 Yields of Radionuclidic Impurities (AS-71,72,74,76 AND B015200100036 SE-75) Produced by He-3 and He-4 Reactions were Given B015200100037 In Figures.
