B010700200008 DETECTOR (SOLST) Intrinsic Germanium Detector Installed in a B010700200009 Massive Shield For Low-Level Counting. B010700200010 Since the Ni-59 Half-Life is not Accurately Known, B010700200011 The Absolute Number of Ni-59 Atoms was Determined by B010700200012 Comparison with a Standard Source, For Which this B010700200013 Number had Been Measured Using the Isotopic Dilution B010700200014 Method with Ni-60 by Means of a Mass-Spectrometer. B010700200015 ERR-ANALYS (EN-ERR) The Uncertainty in Energy at 6 MeV was B010700200016 Estimated to be Less Than 1 MeV. B010700200017 En-Err Value Calculated by the Compiler of Kachapag B010700200018 Using the Tabulated Energy Interval. In Agreement with B010700200019 The Figures Given in the Publication the Center of the B010700200020 Interval was Regarded As Energy Value and the Half of B010700200021 The Interval As the Energy Error.
