    Notes: [Auszug] IN continuation of my letter on the above subject in NATURE of December 18, 1919, several more elements have been subjected to analysis, yielding interesting “mass-spectra.” Argon (atomic weight 39-88 Ramsay, 39-91 Leduc) gives a very strong line exactly at 40, with double charge at 20 ...

    Notes: [Auszug] IT will doubtless interest readers of NATURE to know that other elements besides neon (see NATURE for November 27, p. 334) have now been analysed in the positive-ray spectrograph with remarkable results. So far oxygen, methane, carbon monoxide, carbon dioxide, neon, hydrochloric acid, and ...

    Notes: [Auszug] IN the course of some tests with very sensitive Schumann plates supplied by Messrs. Adam Hilger, I have obtained mass-spectra of mercury of an intensity greater than any previously photographed. On the best of these there are unmistakable traces of two new lines 197 and 203. The first is ...

    Notes: [Auszug] IN the course of my analyses of leads of different origins I have had opportunity of making some interesting observations on these two elements. While preparing a new discharge tube by preliminary running, a mixture of helium and oxygen was used and a search was made for the line due to ...

    Notes: [Auszug] THE preparation by Dr. v. Grosse of suitable volatile compounds of thallium and uranium has enabled me to obtain their mass-spectra. The lines of thallium were obtained by means of its triethyl compound. As was expected, it consists of two isotopes, 203, 205. The latter predominates to an ...

    Notes: [Auszug] THE first mass-speetra obtained from caesium by means of a hot anode showed only one line of mass number 133. As I pointed out,1 the conditions of the experiment precluded any accuracy of measurement sufficient to decide whether the chemical atomic weight then and since accepted, ...

    Notes: [Auszug] THE first mass-speetra of chromium were obtained by means of accelerated anode rays. The results were very feeble and only showed one line of mass number 52 (NATURE, Sept. 22, 1923, p. 449). I have now been able to make experiments with a volatile compound of this metal, the solid carbonyl, ...

    Notes: [Auszug] The first measurements of the relative abundance of the isotopes 6 and 7 of lithium were made by Dempster with his magnetic spectrograph.1 As the instrument indicated ratios so high as 37 and so low as 4.8 with means around 7–10, the results are of little value. ...

    Notes: [Auszug] THESE two elements yield volatile tetroxides and by means of these their mass-spectra have now been obtained. Osmium tetroxide was first experimented with; its action on the discharge, even in the smallest amounts, is quite amazing. The whole mechanism of current flow is violently disorganised ...
