The primary projectile energies usedD063200100014 were 19.0 and 45.0 MeV. D063200100015 SAMPLE High-purity manganese-dioxide powder(99.99%,supplied D063200100016 by Sigma-Aldrich, Germany) and high-purity foils of D063200100017 Mn, Ni, Al,Ti and Cu (99.999%,supplied by Goodfellow, D063200100018 England) were used. D063200100019 In two experiments thin Mn foils (10 mu-m thick) were D063200100020 used. The exact thickness of each foil was obtained byD063200100021 weighing and determining the area. In several other D063200100022 experiments sedimented MnO2 samples were used. The D063200100023 thickness of the MnO2 layer was 5-20 mg/cm2. It was D063200100024 homogeneous and mechanically stable. The layer was D063200100025 covered by a 10 mu-m thick and 16 mm in diameter D063200100026 Al foil. Thus each sample consisted of an Al-MnO2-Al D063200100027 sandwich. D063200100028 METHOD (STTA) Two stacks of Mn foils and several stacks of D063200100029 the sedimented manganese-dioxide samples together withD063200100030 the absorbers and monitors were irradiated D063200100031 DETECTOR (HPGE) The absolute efficiency curves of the detector D063200100032 were determined at source-detector distances of 5, 10,D063200100033 15, 20 and 30 cm using gamma-ray standards supplied byD063200100034 the PTB Braunschweig or Amersham International. D063200100035 (SILI) Used for X-ray spectrometry. It had an active D063200100036 diameter of 4 mm, a depth 4.59 mm and was covered D063200100037 by a 12.7 mm thick Be film.
