Abstract
The results of calculating the energy and space distribution of gamma rays in the 0. 1 - 300 MeV bandwidth arising from various processes in the galaxy are presented. The processes considered are the Compton scattering of the 2. 7 degree K background photons and of starlight by cosmic ray electrons, and the decay of neutral pions produced in the nuclear interaction of cosmic rays with interstellar matter. Particular emphasis is given to the strong increase in the density of stellar photons close to the galactic center. This leads to a peaking of the gamma-ray fluxes in the direction from around the center. The calculated spectral shapes and the angular distributions are in agreement with the available observations in the bandwidth similar 10 - 100 MeV.
