Mesoatoms

The general provisions of this review apply, as a rule, to negative mesons of any type. More detailed remarks, especially those related to numerical estimates, apply only to $\mu$- and $\pi$-mesons, unless otherwise specifically stated.

Theories of the Liquid State

The aim of the present review of theories of the liquid state is to critically compare the theories proposed by various authors and, in particular, to consider which of them are capable of providing, in terms of intermolecular forces, a quantitative explanation of the well-known thermodynamic proper…

SCATTERING OF $\pi$ MESONS BY NUCLEONS

This review is devoted to a discussion of both experimental studies of the scattering of $\pi$-mesons by nucleons and attempts at a theoretical interpretation of the regularities observed in the experiments. An attempt is made to find an extrapolation formula for the dependence of the total cross se…

Conference on the Liquid State of Matter

On May 28–30, 1953, a conference on the liquid state of matter was held in Kyiv, convened by the Academy of Sciences of the Ukrainian SSR and T. G. Shevchenko Kyiv State University.

Theories of the Liquid State

The aim of this brief review is to supplement the review article by J. de Boer presented above with the results of certain works that were not included in that article or were published after it was written. Such a supplement seems to us all the more necessary because, of the two main directions in …

PHOTOPRODUCTION OF $\pi^0$ MESONS ON HYDROGEN AT ENERGIES UP TO 450 MeV

STATISTICAL THEORY OF ATOMIC NUCLEI\*)

The statistical theory developed in the present work is, by its very nature, applicable primarily in the region of nuclei with a large number of particles. The fact that it also gives good results for light nuclei is a consequence of our introduction of two corrections: namely, we introduced a corre…

ON MAGNETO-OPTICAL PHENOMENA IN FERROMAGNETS

This work provides the most general formal macroscopic description of magneto-optical phenomena without invoking any microscopic models.

“On Philosophical Errors in the Works of Academician L. I. Mandelstam”

Academician L. I. Mandelstam has outstanding merits in the development of Soviet physics, the creation of a school, and the training of scientific personnel. In his scientific research in specialized fields of physics—optics, statistical physics, and radiophysics—L. I. Mandelstam appears as a sponta…

FISSION NEUTRON SPECTRUM OF Pu$^{239}$

Statistical Physics of a Linear Polymer Chain

This article constitutes the first part of a review, in which the statistical theory of an isolated linear chain molecule will be considered. The second part of this review will be devoted to the statistical theory of the mechanical properties of a macroscopic sample and, finally, the third part to …

ON NONLOCAL FIELDS AND THE COMPLEX NATURE OF “ELEMENTARY” PARTICLES

At present, there are two sharply distinct directions in field theory. One direction is associated with various kinds of “subtraction operations,” with various methods of regularizing known divergent expressions. The other direction is associated with the ideas of a nonlocalized field, with various …

Conference on Ultrasonic Flaw Detection and General Problems of Ultrasonics

An expanded meeting on ultrasonic flaw detection and certain other problems of ultraacoustics, convened by the Commission on Acoustics of the Academy of Sciences of the USSR, was held in Moscow.

HEAVY MESONS

Research over the past two years has decisively changed the state of affairs and has not only shown that the heavy meson exists, but moreover has shown that there are charged heavy mesons of different masses and that, in addition, neutral heavy mesons also exist, likewise with different masses.
