Current State of the Theory of Intranuclear Forces

This review considers works by various authors carried out over the past four years and aimed at elucidating the nature of the forces of interaction between the particles that constitute the atomic nucleus, as well as the general features of a theory that would make it possible to describe the nucle…

Remarks on the Theory of the Atomic Nucleus\*

The abundance of experimental material collected on atomic nuclei reveals an increasingly clear picture of the laws determining their structure. Therefore, below we shall attempt to give a brief comparison of modern theoretical views on the structure of the atomic nucleus, some of which have already…

Absorption and scattering of $\gamma$ rays

The $\gamma$ -rays emitted by certain radioactive substances are known to be electromagnetic radiation of very short wavelength. When passing through matter, $\gamma$ -rays are partly absorbed in it and partly scattered. The aim of our article is to consider the absorption and scattering of $\gamma$…
