Gamma-ray evidence for galactic fermi acceleration of cosmic rays

Conference ·
OSTI ID:4164299
New information on the distribution of cosmic rays in the galaxy is provided by SAS-2 galactic gamma-ray data. The observed gamma-ray energy spectrum reveals that about 70 percent of the radiation in the central galactic region arises from the decay of neutral pi mesons produced by cosmic ray nucleon interactions with the interstellar gas.
