Abstract
The arguments, obtained in favor of the hypothesis on internuclear interaction of atoms (offered by author in the preceding publication), are presented. It is proposed an interpretation of physical phenomenon Bragg peak, which is discovered 100 years ago but is not understood hitherto. An extremely simple and natural explanation of chemical covalent bond (which unlikely may be considered satisfactory at present) is produced.
Key words: Internuclear interaction, π0-mesons, Brag peak, chemical bond.
