STANDING LIGHT WAVES; REPETITION OF WIENER’S EXPERIMENT ON A PHOTOELECTRIC SURFACE*

The main content of this article may to some extent be regarded as preliminary material for further research on cesium–silver–oxide photocells.

All this unquestionably indicates that the author’s criticism was not preceded by any serious study of the question.

DISINTEGRATION OF ATOMS BY COSMIC RAYS AND THE POSITIVE ELECTRON\*

We have recently developed a method by which the very fast particles accompanying cosmic radiation can be made to photograph themselves, or, more precisely, the traces of their own paths in a Wilson chamber. In this case, photographs of the tracks can be obtained much more easily than by the ordinar…

THE DEVELOPMENT OF X-RAY ANALYSIS OF CRYSTALS

The article published below, kindly sent by Prof. W. H. Bragg for our journal, is of particular interest, since its author is not only one of the principal participants in the discovery of X-ray analysis, but has also since then consistently continued to play a leading role in the development and ap…

PASSAGE OF COSMIC RAYS THROUGH MATTER

The question of the nature of cosmic rays is closely connected with the question of the passage through a material medium of fast protons, fast electrons, and quanta with high energy. By studying the alpha, beta, and gamma rays of radioactive elements, we can, partly by extrapolation and partly by t…

New Electrovacuum Devices with a Hot Cathode in a Rarefied Gas

The modern development of the physics of electronic and ionic processes, and in particular the physics of electrical discharges in gases, has led to the development of new types of electrovacuum devices, while at the same time significantly expanding the scope of their technical application.
