Local gamma-ray sources [PDF]

Il Nuovo Cimento C, 2010
The quiet Sun, the Moon, the Earth and other Solar System objects are sources of high-energy gamma rays. The emission is produced by interactions of Galactic cosmic rays: by nucleons in the surface and atmosphere of the sources via hadronic interactions, and by electrons on solar photons in the heliosphere via inverse Compton scattering. Both emissions

Directional Detector of Gamma Ray Sources

Health Physics, 1996
This work describes the design, development, and characterization of an ionization chamber to detect and locate gamma ray sources with intensities down to 100 mu Gy h(-1). The results show that sources of x ray and gamma radiation in the energy range of 14 to 1,250 keV can be located.

Point-like gamma-ray sources

Space Science Reviews, 1983
Various models are examined, which could give rise to point-like gamma-ray sources, at the present time indistinguishable, experimentally, from true point sources. These models involve energetic processes associated with interstellar clouds, e.g. supernova-cloud interactions, neutron star accretion inside interstellar clouds, cloud collisions, etc. The
