Cosmic Rays and Their Interaction.

This 1968 monograph is a fundamental work in the field of high-energy astrophysics, authored by two preeminent Soviet physicists, Vladimir Murzin and Lidiya Sarycheva. At a time when space exploration and particle physics were rapidly converging, the text provides a deep dive into the internal logic of cosmic radiation, including the arrangement of the primary cosmic ray spectrum and the complex secondary processes triggered as these particles strike the Earth's atmosphere. Vladimir Murzin, a corresponding member of the Academy of Sciences and a pioneer in the field, alongside Lidiya Sarycheva, an expert in high-energy particle interactions, synthesized decades of Soviet and international research to create this systematic guide. The book was published by Atomizdat, the primary state press for nuclear and atomic science, during the height of the Soviet Union's leadership in space-based scientific research.
Across its 391 pages, the volume explores the composition of primary radiation, the mechanisms of particle acceleration in the galaxy, and the theoretical models of nuclear interactions at energies far beyond what could be achieved in terrestrial accelerators of the era. The authors pay particular attention to experimental methods, detailing the operation of detectors and the analysis of extensive air showers (EAS). Based largely on the authors' original research conducted at Moscow State University and specialized high-altitude stations, the work remains a vital primary source for historians of science. Given the small print run of 2,600 copies and its high technical density, this 1968 Moscow imprint is a significant bibliographical rarity. For bibliophiles, physicists, and collectors of scientific heritage, it documents the period when cosmic rays were the "natural laboratories" that paved the way for modern quantum field theory and cosmology.
