    Notes: [Auszug] THE method outlined in our letter of September 30, 1920 (NATURE, vol. cvi., p. 144), and used for the partial separation of the isotopes of mercury, has enabled us to accomplish a partial separation of the isotopes of chlorine. When about half of a strong solution of hydrochloric acid cooled ...

    Notes: [Auszug] WE have been successful in achieving a partial separation of the isotopes of mercury by evaporating, mercury at low pressure and condensing the evaporated atoms on a cooled surface. The rate of evaporation of the isotopes being inversely proportional to the square root of their atomic weight, ...

    Notes: [Auszug] THROUGH the courtesy of the editor of NATURE we have been able to see an advance proof of the letter of MM. Urbain and Dauvillier (NATURE, February 17, p. 218), and are glad to have the opportunity to add the following comment: Our main reasons for believing that the element celtium, the ...

    Notes: [Auszug] IN a former letter to NATURE (January 20, p. 79) we announced the discovery of a new element with atomic number 72, for which the name hafnium was proposed. Evidence was given that this element is a homologue of zirconium in accordance with theoretical expectations (Bohr, “Theory of Spectra and ...

    Notes: [Auszug] SINCE Moseley's discovery of the fundamental laws of the X-ray emission, it has become quite clear that the most simple and conclusive characteristic of a Chemical element is given by its X-ray spectrum. In addition, Moseley's laws allow us to calculate very accurately the wave-lengths of the ...

    Notes: [Auszug] THE successful accomplishment of separating the isotopes of mercury (NATURE, 106, 144, 1920; Phil. Mag. 43, 31, 1922) suggested an investigation to determine the extent to which samples of mercury from different sources might show the same atomic weight, i.e. the same density, which is to be ...

    Notes: [Auszug] THE investigation of a very great number of ores containing zirconium has revealed the presence of hafnium without exception. (Comp. the December issue of the Journ. Chem. Soc., 1923.) The hafnium content, which could be readily estimated by quantitative X-ray spectroscopy as devised by Coster ...

    Notes: [Auszug] INVESTIGATIONS carried out by Ellis (Proc. Roy. Soc. 101, 1, 1922) at the Cavendish laboratory lead to the conclusion that quantum dynamics probably apply to the nucleus of the atom and lend support to the assumption that the emission of γ-rays from the nucleus precedes the disintegration ...
