    A Radioactive Isotope of Iron (1936)
    [s.l.] : Nature Publishing Group
    Nature 138 (1936), S. 76-77

    Notes: [Auszug] IT was shown by Fermi and co-workers1 that the activity induced in iron by neutron bombardment is due to an isotope of manganese. The isolation of an active iron isotope has not been reported. By means of the sensitive tube counter outfit2 in this institute, it was ...

    Induced Radioactivity of Mercury (1936)
    [s.l.] : Nature Publishing Group
    Nature 137 (1936), S. 457-457 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] BY means of a sensitive tube counter outfit in which the effects of penetrating cosmic radiation are partially compensated1, it was found that mercury (as HgO) could be activated by neutron bombardment, the active product decaying with a period of 40 ± 5 hours. The irradiated ...

    Eine empfindliche Zählrohranordnung (1936)
    Springer
    The European physical journal 98 (1936), S. 597-604 
    Details
    ISSN: 1434-601X

    Topics: Physics
    Notes: Zusammenfassung Das Zählrohr, mit welchem man Messungen ganz schwacher Radioaktivitäten vorzunehmen beabsichtigt, wird auf geeignete Weise mit einer Reihe anderer Zählrohre umgeben. Man verwendet einen Verstärker, der nur die Impulse des ersten Zählrohres zählt, soweit sie nicht mit Stößen in einem der umgebenden Zählrohre koinzidieren. Durch Verwendung von Bleipanzern und dieser Kompensation für Koinzidenzen kann der natürliche Effekt, der mit einem Zählrohr gemessen wird, auf etwa ein Fünftel des Wertes, den man ohne Schutz erhält, herabgesetzt werden.
