Book excerpt: "The scientific potential of y-ray astronomy has long been recognized from a theoretical standpoint by investigators in the fields of cosmic-ray research and high-energy astrophysics. Gamma-ray studies can help answer questions concerning the nature and origin of cosmic rays, both galactic and extragalactic : the nature of supernovae, pulsars, and powerful radio sources; the extent and importance of antimatter in the universe; and the nature of the universe in the distant past. The advent of satellite-borne y-ray telescopes has recently made y-ray astronomy a reality. The first observations, as discussed in this book, have already provided important information on galactic and extragalactic cosmic rays and interstellar gas. These observations may also have great cosmological significance. The second generation of y-ray telescopes is already in the development stage. It therefore seems most appropriate at this time for a comprehensive theoretical monograph."--Page iii.

Available in PDF, EPUB and Kindle. Book excerpt: Various cosmological situations are discussed in which the annihilation of anti-matter will produce cosmic gamma-rays. It is shown that the production of mesons other than pions have little effect on the annihilation gamma-rays spectrum. It is also shown that gamma rays arising from annihilations at rest have energies between 5 and 865 MeV. The gamma-rays spectrum from annihilations at rest is calculated and compared with the calculations of Frye and Smith. A discussion is then presented of the various characteristics of proton-antiproton interactions in flight. Production of various mesons, hyperons, and isob isobars is discussed and cross sections are given. General implications of the data on the resultant gamma-ray spectra are stated.

Available in PDF, EPUB and Kindle. Book excerpt: Calculated the galactic gamma-ray spectrum due to the decay of the nucleon isobars N*1/2 (1.410) and N*1/2 (1.688), for which the excitation involved no change of isotopic spin or strageness and due to the decay of hyperons (Lambda, Sigma+, Sigma0). Results show that these reactions may be an important source of gamma rays of energy greater than 6 TeV (6 X 10(12) eV).

Book excerpt: Cosmic Rays is a two-part book that first elucidates the discovery, nature, and particles produced by cosmic rays. This part also looks into the primary cosmic radiation; radio waves from the galaxy; extensive air showers; origin of cosmic rays; and other cosmic radiations. Part 2 consists of reprinted papers involving cosmic rays. Papers 1 to 10 treat the nature of the radiation, arranged chronologically; in Papers 11 to 16 the scene moves away from the Earth.

Book excerpt: In 1912 Victor Franz Hess made the revolutionary discovery that ionizing radiation is incident upon the Earth from outer space. He showed with ground-based and balloon-borne detectors that the intensity of the radiation did not change significantly between day and night. Consequently, the sun could not be regarded as the sources of this radiation and the question of its origin remained unanswered. Today, almost one hundred years later the question of the origin of the cosmic radiation still remains a mystery.Hess' discovery has given an enormous impetus to large areas of science, in particular to physics, and has played a major role in the formation of our current understanding of universal evolution. For example, the development of new fields of research such as elementary particle physics, modern astrophysics and cosmology are direct consequences of this discovery. Over the years the field of cosmic ray research has evolved in various directions: Firstly, the field of particle physics that was initiated by the discovery of many so-called elementary particles in the cosmic radiation. There is a strong trend from the accelerator physics community to reenter the field of cosmic ray physics, now under the name of astroparticle physics. Secondly, an important branch of cosmic ray physics that has rapidly evolved in conjunction with space exploration concerns the low energy portion of the cosmic ray spectrum. Thirdly, the branch of research that is concerned with the origin, acceleration and propagation of the cosmic radiation represents a great challenge for astrophysics, astronomy and cosmology. Presently very popular fields of research have rapidly evolved, such as high-energy gamma ray and neutrino astronomy. In addition, high-energy neutrino astronomy may soon initiate as a likely spin-off neutrino tomography of the Earth and thus open a unique new branch of geophysical research of the interior of the Earth. Finally, of considerable interest are the biological and medical aspects of the cosmic radiation because of it ionizing character and the inevitable irradiation to which we are exposed. This book is a reference manual for researchers and students of cosmic ray physics and associated fields and phenomena. It is not intended to be a tutorial. However, the book contains an adequate amount of background materials that its content should be useful to a broad community of scientists and professionals. The present book contains chiefly a data collection in compact form that covers the cosmic radiation in the vicinity of the Earth, in the Earth's atmosphere, at sea level and underground. Included are predominantly experimental but also theoretical data. In addition the book contains related data, definitions and important relations. The aim of this book is to offer the reader in a single volume a readily available comprehensive set of data that will save him the need of frequent time consuming literature searches.
