Superconductivity transitions were observed by an oscillography to be anomalous in the transition from one condition to another.

The author introduces an equation for the calculation of atomic radii of crystalline elements

Extraneous particles, contained in Helium II, come into its normal part. Since the normal part of helium II, bound with phonons and rotons, quickly diminishes with decreasing temperature, and the contributions of the extraneous particles in the normal part, with decreasing temperatures does not decrease (but further increases).

In previous works the authors presented theories on collisions. In this paper the authors will discuss the determination of the effective cross section with exponential accuracy without the slowly varying coefficient.

To obtain a temperature less than 1°K and to conduct the research at these temperatures at present is connected with significant difficulties. Though the magnetic method of Debye and Gistique can reach very low temperature, it posses an inadequate range, which makes desirable the use for research, requiring uniformity of temperature in the course of long measurements, of the method of pumping vapor over liquid helium.

Two isotopic atoms or molecules which are compared in different ways from isotopic atomic species (N2O and D2O) are chemically identical. The author examines the statement a little more closely, and finds that it would be more proper to that these atomic species are practically identical.

The atoms of a stable chemical element usually consist of several types, which are distinguished by their weight. These types are called the isotopes of the element in question. In this paper the author's focus with the measurement of isotopes with the use of a mass spectrograph.

A description is given of an ion source in which the ions are generated by electron bombardment of a molecular beam or gas stream at low pressure.

On the specificity of phenomena, occurring in the case of cathodes of low conductivity, the article considers the problem of ionization of atoms and neutralization of ions on their surfaces. At the same time the author demonstrates the peculiarities of these phenomena and their distinctness from the case of metallic surfaces.

The oxide thermocathode is the main element of numerous present day electronic instruments and installations. The work presented in this paper is an attempt to investigate the various phenomena which take place inside an actual thermocathode during electronic emission.

An imperfect articulated joint may be considered as a prism stressed by a load acting only on part of its surface. The author carried out tests with a prismatic model acted on by an axial force.

Adsorption passivation of metals is discussed in this paper.

A short survey of diffusion processes in the atmosphere the coagulation of aerosol particles, the evaporation thereof and the evaporation of droplets from the view point that isotropic turbulence in involved.

The gasification of liquid oxygen is carried out by means of its supply from the storage vessel to the vaporizer (generally consisting of a heat exchanger from copper tubes, heated by water), where the conversion to gaseous state takes place.

A new formulation is given of the theory of mass spectrographs which are double focusing for all massess.

The physics of rays offered new ways of therapy by high-frequency and ultra-frequent currents. With the discovery of the spontaneous slow radioactive decay of certain elements, a new start was given for the study and the treatment of cancer and other diseases.

This article is a discussion of the focusing properties of the electrical field having axial symmetry with a radial component proportional to the distance from the axis,

The equations of Proka in the field of the plane wave are considered in this paper. When the energies of the incident quantum are large, a solution is reached in a closed form. On the basis of the solutions obtained, the diffusion of light on a meson is evaluated by the method of delayed potentials.

In the present article the principle of designing a new type of mass spectrograph is discussed, in which the movement not of ions but neutral atoms (or molecules) possessing magnetic movement.

It appeared of interest to investigate the functional relationship which the authors observed between the hardness and the difference of potential for various pure metals over a fairly wide range of potentials, including the electrocapillary maxima.

The construction of a heavy electro-magnet is a well known problem of which the authors will deal only with the methods applicable to the cyclotron.

Structures and internuclear distances for several inorganic fluorides have been determined by electron diffraction method.

Tests are made on a new version of the Mattauch-Herzog double-focusing mass spectrograph for precision mass determinations.Special effort was directed toward achieving exact and stable mechanical construction, complete adjustability and a stable vacuum.

A description of the character of the bond as a superposition of homopolar and ionic bonding is a very useful approximation in quantum-mechanical research on the properties of molecules. In the LiH molecule, it may be assumed with sufficient accuracy that the bond is formed by two electrons, since, besides the outer electrons composing the bond, there is only a closed layer of inner electrons in the lithium atom.
