    Isomorphic Relationship between Rubidium and Thallium in Igneous Minerals (1945)
    [s.l.] : Nature Publishing Group
    Nature 155 (1945), S. 610-610 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] V. M. GOLDSCHMIDT1 has been able to demonstrate that the radius of an ion is a fundamental factor in regulating isomorphic behaviour, ions of like size being capable of replacing each other isomorphically within a crystal lattice. The application of this law of crystal chemistry ...

    Determination of the Age of Minerals by means of the Radioactivity of Rubidium (1946)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] THE suggestion has been advanced by Goldschmidt1 that the radioactive decay of rubidium into strontium might be utilized as means of determining the age of minerals. Hahn and Walling2 have discussed the problem and assess the half-life period of rubidium as 2.3 × ...

    Geological Age: the Extreme Antiquity of Pegmatites from Manitoba (1947)
    [s.l.] : Nature Publishing Group
    Nature 160 (1947), S. 874-875 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] AN inspection of the available data on geological ages determined by the lead method shows that in two areas the pegmatite ages appear to be considerably greater than those of any other Pre-Cambrian pegmatites so far determined. These two areas are located in northern Karelia and south-east ...

    Evidence of Geological Age against Decay of Tin-115 to Indium-115 by Electron Capture (1948)

    Notes: [Auszug] ACCORDING to a rule of nuclear stability, it is improbable that two neighbouring elements (neighbouring Z) have stable isotopes of the same nominal mass, that is, stable neighbouring isobaric pairs should not exist. A few apparent exceptions to this rule are known, one of which is the pair, ...

    Neutron Numbers 98, 108 and 116 (1963)

    Notes: [Auszug] The possibility that AT = 98 and N- 116 might be significant had in fact already been briefly noted by me2 in a systematic study of the relative abundances (per cent proportions) of the isotopes of the elements. It is the purpose here to consider further the probability that these neutron numbers ...

    Notes: [Auszug] It is contended that if two straight-line segments (or close approximations to straight-line segments) of distinctly different slope are obtained when the raw data are examined on cumulative frequency paper, the distribution of the raw data may be satisfactorily described in terms of parts of two ...
