Measured Beta-Delayed Alphas B009100200005 From Dissociation of be-8 Formed in Beta-Decay of B-8. B009100200006 FACILITY (CCW,2GERMST) B009100200007 SAMPLE Be-7-Oxide, Thickness (2.37+-0.21)E16 Atoms be-7/Cm**2 B009100200008 Deposited on 0.2 mm Tantalum in a Spot of 4 mm in B009100200009 Diameter. B009100200010 Be-7 was Produced by Irzadiating Metallic Li with B009100200011 7.5 MeV Protons from the Bochum Dynamitron. The Yield B009100200012 From a 40 Hr Bombardment at 20 Micro-Amps was 0.5 B009100200013 Micrograms. B009100200014 The Thickness was Determined from the Activity of the B009100200015 478 KeV Gamma-Rays Having an Abundance of 0.104. B009100200016 The Inhomogeneity in Thickness was Determined to be B009100200017 Less Than 3 %. B009100200018 DETECTOR (SOLST).Surface Barrier Detector, Thickness 0.2 mm B009100200019 ERR-ANALYS (DATA-ERR) The Error Consists Mainly of the StatisticalB009100200020 Error of About 0.02 Microbarns and of the Same Amount B009100200021 Due to the Uncertainty in the Number of be-7 Nuclei PerB009100200022 Cm**2. B009100200023 CORRECTION Background Correction For the Delayed Alpha Particle B009100200024 Spectrum was Achieved by Recording a Spectrum While B009100200025 The Accelerator was Turned Off. Apart from Noise at B009100200026 Low Energies No Background Count Above 0.95 MeV was B009100200027 Observed.
