Was B011200100012 Degraded by be-Absorbers. The Used Energy-Range B011200100013 Relation is not Quoted. B011200100014 The Fission Product Yields were Measured on-Line with B011200100015 A Mass Spectrometer, the Mass-Discrimination EfficiencyB011200100016 Of Which was Calibrated with the Isotopes of Natural B011200100017 Ba and Sn. The Mass-Separated Ions were Counted by B011200100018 Means of an Electron Multiplier. B011200100019 The Identification of the Separated in-Isotopes was B011200100020 Confirmed by Measuring Their Radioactive Decay, That B011200100021 Of the Ga-Isotopes was Based on the Chemical SimilarityB011200100022 Of Ga and in. B011200100023 No Information is Given Whether and How the Proton B011200100024 Flux was Determined and Accounted For. It was Possibly B011200100025 Regarded by the Normalization Procedure Applied (SEE B011200100026 COMMENT UNDER REACTION) And Therefore not Measured B011200100027 (COMMENT BY THE COMPILER OF KACHAPAG) B011200100028 SAMPLE Natural U-Oxide Deposited in Layers of About 5.4 B011200100029 Mg/Cm**2 on 28.6 Mg/Cm**2 Thick Graphite Disks of 12.7 B011200100030 Mm Diameter. A Total of 23 Disks were Assembled As B011200100031 Target Within the Oven of the on-Line Mass-Separator. B011200100032 CORRECTION The Measured Relative Independent Yields were CorrectedB011200100033 For Diffusion Times in the Target Assembly, Decay of B011200100034 The Radioactive Isotopes, and the Mass-Discrimination B011200100035 Of the Separator. No Corrections were Applied For the B011200100036 Cumulative Yields. Their Contributions were Believed toB011200100037 Be Small Due to the Fact That Yields were Measured B011200100038 During and Between Prompt Beam Pulses (PULSE DURATION- B011200100039 0.2 SEC, PULSE DISTANCE- 2 SEC) And That by B011200100040 Subtracting the Off-Beam Yield Cumulative Events and B011200100041 Background Should Mostly be Cancelled. Furthermore, theB011200100042 Precursors Should have Much Longer Diffusion Times. B011200100043 ERR-ANALYS (ERR-S) The Given Errors Represent Only the Relative B011200100044 Errors Due to Statistics. Not Included are Errors B011200100045 Resulting from the Normalization Procedure. B011200100046 Systematic Errors Due to the Energy Loss of the ProtonsB011200100047 In the Target, Especially at Lower Beam Energies, B011200100048 Resulting in a Widening of the Isotopic Distribution, B011200100049 Are Also Disregarded.
