    Notes: [Auszug] IN continuation of our letter on the above subject which was published in NATURE of November 11, 1933, p. 747, we wish to add the following remarks : We have changed the term ‘electrodivision of quantum’ used in that letter to ‘electrofission of quantum’. TFnder the intense electrical ...

    Notes: [Auszug] IT is well known that for the excitation of the characteristic X-ray spectra of elements, an electron has first to be removed from some internal level; when this is done, an electron from an outer level jumps to this vacant place, and characteristic radiation is emitted. The spectrum is called ...

    Notes: [Auszug] FRANCK and his co-workers have shown that the vapours of alkali halides show a continuous absorption spectrum beginning from a long waverlength limit and extending towards the ultra-violet. He interpreted the absorption spectrum as follows : if we take a substance like sodium chloride the ...

    Notes: [Auszug] IN continuation of the letter published in NATURE, vol. 125, p. 163, Feb. 1, 1930, we wish to report that absorption spectra of vapours of chromic chloride and ferrous chloride were taken at temperatures of 1000° C. to 1400° C. in the vacuum furnace in order to test the theory postulated in the ...

    Notes: [Auszug] IT is well known that the spectrum of the upper layers of the solar chromosphere is chiefly composed of those lines which are relatively more strengthened in the spark than in the arc, and which Sir Norman Lockyer originally styled enhanced lines. The best-known examples are the calcium H and K ...

    Notes: [Auszug] It appears that if the identification of the stripped nucleus of neon as one of the main constituents of primary cosmic particles be correct, and is confirmed by subsequent observations, it constitutes a very strong argument against the hypothesis that the sun is the source of cosmic particles ...

    Notes: [Auszug] THE difficulties which have so far been experienced in working out a physical theory of the solar corona (vide Rosseland, “Theoretical Astrophysics”, Chap. 14) have apparently been increased by the discovery of Grotrian and Edlén that many of these lines are due to forbidden transitions of ...

    Notes: [Auszug] RECENT work in this laboratory has shown that the irregular doublet law, first discovered in 1920 by G. Hertz in the X-ray region, and since then extended by Millikan and Bowen for the optical region, is capable of much wider application. Millikan and Bowen have applied the law for the ...
