Physicists of Cosmic Ray Division publish tenth paper in Physical Review journal of American Physical Society (APS).

The Constitution of the APS states that the objective of the Society shall be the advancement and diffusion of the knowledge of physics. Research results should be recorded and maintained in a form that allows analysis and review, while experimental data should be immediately available to 

scientific collaborators. Following these principles, Armenian physicists have presented detailed descriptions of their discoveries on Natural Gamma Radiation (NGR) and particle fluxes of the last decade in 10 issues of the Physical Review journal. The discovery of the Thunderstorm 

Ground enhancements (TGEs) registered by a variety of particle detectors located on Mt. Aragats and explanation of the TGE origin were published in first two papers. Another two papers proved registration of the neutron component of TGEs, explaining that photonuclear reactions of the 

gamma rays are responsible for the neutron flux. The structure of the electric field inside thundercloud and energy spectra of the electrons and gamma rays were described in subsequent papers. The lightning initiation is directly related to the geomagnetic avalanches in the lower part of the 

thundercloud, that was demonstrating by the special TGE events abruptly terminated by the atmospheric discharges.  The last papers on this research topic were devoted to long-lasting TGEs and Radon progenies’ contribution to the winter enhancements of particle fluxes.

The entire history of the development of the new scientific discipline, namely, the High-Energy Physics in Atmosphere (HEAP) and the revealing the sources of the NGR can be followed by CRD’s publications in Physics Reviews journal of American Physical Society (see references below).
