Abstract
Results on cosmic gamma rays have been taken with data, available for the first time, on the distribution of molecular hydrogen over a significant region of the Galactic plane, to study the distribution of cosmic rays in the Galaxy. It is found that there is strong evidence for a lower cosmic-ray intensity in the outer Galaxy, suggestive of a Galactic origin for the particles.Keywords
