It is shown that there is evidence favouring molecular clouds being sources of γ-rays, the fluxes being consistent with expectation for ambient cosmic rays interacting with the gas in the clouds for the clouds considered. An estimate is made of the fraction of the apparently diffuse γ-ray flux which comes from cosmic ray interactions in the I.S.M. as distinct from unresolved discrete sources. Finally, an examination is made of the possibility of gradients of cosmic ray intensity in the Galaxy.

Cosmic Ray Flux

The cosmic ray flux in the galactic centre region is predicted from the observed data for high energy y rays, y-ray lines and massive molecular clouds. The predicted cosmic ray fluxes above 1 GeVand below 100 MeV are two and four orders of magnitude respectively larger than the value in the neighbourhood of the solar system. The corresponding energy density of cosmic rays is estimated to be 100 eV cm- 3 ? Such a concentrated stream of cosmic rays could accelerate the dense and massive molecular clouds by transfer of their momentum.
