5.6 Mass Spectrographs

Description: In recent years German physicists have been making increasing use of both mass spectrographs in the stricter sense and mass spectrometers which can only measure elative isotopic abundances and use electrical methods of measurement.

About an Intense-Light, Silent Discharge Tube for the Spectroscopic Examination of Small Amounts of Substances

Description: One of the problems in the spectrographic investigation of the atomic nucleus is to increase the efficiency of the source of light used for the investigation. Using new procedures outlined in the article new elements may be detected through nuclear change.

About the Importance of Unstable Peroxides of Green Leaf of Plant for Photosynthesis

Description: A. N. Back expressed a hypothesis about the participation of organic peroxide in the process of photosynthesis. Experimental data on this question were very few. This article provides a method of investigation to support the hypothesis.

About the Model of Bacterial Photosynthesis

Description: At the base of photosynthesis of green sulfur bacteria lies an oxidation-reduction reaction of transferring hydrogen from hydrogen sulfide to carbon dioxide, accomplished with the participation of light energy. Based on experiments the author concludes that chlorophyll in the process of photosynthesis plays the role of optical sensitizer.

The Activation of the Rare Earths by Thermal Neutrons

Description: The present knowledge of artificial radio-activity is more spotty for the rare earths than for any other region of the periodic table. The chief reason for this is the difficulty of obtaining sufficiently pure samples or at any rate such of well-known composition. Rare earthers were investigated through the activation by thermal neutrons.

An Anode-Channel Source for Positive Ion Beams

Description: The dependence of the ion output on several variables was studied thoroughly and the point of optimum operatio was determined. Mercury ions were used and certain observed effects were ascribed to the presence of heavier ions.

Cathode Sputtering Problems

Description: The question of the nature and charge of the metallic particles emitted in cathode sputtering has been answered experimentally: the particles are primarily neutral atoms. The proof was obtained from the moving particles themselves by a new "spectroscopic method of vapor pressure measurement" in combination with a "vapor pressure measurement from coating density."
