Available in PDF, EPUB and Kindle. Book excerpt: Neutrons produced by the interaction of primary cosmic rays with atmospheric nuclei have been measured at energies from 10 to 100 MeV and angles from 20 degrees to 80 degrees to the vertical. The data were taken on a balloon flight from Palestine, Texas, 40 degrees North geomagnetic latitude, on September 26, 1971. A telescope constructed of two large area tanks of liquid scintillator measured the incident neutron's energy and direction. Results of calibrations with neutrons of 55 and 15.3 MeV are presented.

Book excerpt: The measurements of the energy spectra and angular distributions of earth albedo neutrons from 10 to 100 MeV are reported. The measurements were made at 40 degrees N. geomagnetic latitude from a balloon at 120,000 ft. (below 4.6 g/sq. cm. of the residual atmosphere). The fluxes of upward moving neutrons at angles of 20 degrees to 70 degrees to the vertical show that the intensities of lower energy neutrons are peaked near the vertical. The distributions are integrated over angle to give a vertical energy distribution for upward moving neutrons that is flat to 50 MeV, then drops off with energy. The absolute neutron flux is of the correct strength and the energy distribution is of the correct shape for the albedo neutrons to be the source of the protons trapped in the earth's inner radiation belt. An upper limit for solar neutrons from 20 to 60 MeV for the quiet sun on September 26, 1971 is 1.0 x 10 to the minus 3rd power neutrons/sq. cm.-s with a 95% confidence limit. (Author).

This book was released on 2013-03-19 with total page 891 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present monograph as well as the next one (Dorman, M2005) is a result of more than 50 years working in cosmic ray (CR) research. After graduation in December 1950 Moscow Lomonosov State University (Nuclear and Elementary Particle Physics Division, the Team of Theoretical Physics), my supervisor Professor D. I. Blokhintsev planned for me, as a winner of a Red Diploma, to continue my education as an aspirant (a graduate student) to prepare for Ph. D. in his very secret Object in the framework of what was in those time called the Atomic Problem. To my regret the KGB withheld permission, and I, together with other Jewish students who had graduated Nuclear Divisions of Moscow and Leningrad Universities and Institutes, were faced with a real prospect of being without any work. It was our good fortune that at that time there was being brought into being the new Cosmic Ray Project (what at that time was also very secret, but not as secret as the Atomic Problem), and after some time we were directed to work on this Project. It was organized and headed by Prof. S. N. Vernov (President of All-Union Section of Cosmic Rays) and Prof. N. V. Pushkov (Director of IZMIRAN); Prof. E. L. Feinberg headed the theoretical part of the Project.

Available in PDF, EPUB and Kindle. Book excerpt: Short Historical Overview In the 1940s, two phenomena in the ?eld of cosmic rays (CR) forced scientists to think that the Sun is a powerful source of high-energy particles. One of these was discovered because of the daily solar variation of CR, which the maximum number of CR observed near noon (referring to the existence of continuous ?ux of CR from the direction of the Sun); this became the experimental basis of the theory that CR’s ́ originate from the Sun (or, for that matter, from within the solar system) (Alfven 1954). The second phenomenon was discovered when large ?uxes of high energy particles were detected from several solar ?ares, or solar CR. These are the - called ground level events (GLE), and were ?rst observed by ionization chambers shielded by 10 cm Pb (and detected mainly from the secondary muon-component CR that they caused) during the events of the 28th of February 1942, the 7th of March 1942, the 25th of July 1946, and the 19th of November 1949. The biggest such event was detected on the 23rd of February 1956 (see the detailed description in Chapters X and XI of Dorman, M1957). The ?rst phenomenon was investigated in detail in Dorman (M1957), by ?rst correcting experimental data on muon temperature effects and then by using coupling functions to determine the change in particle energy caused by the solar-diurnal CR variation.
