Scientific paper

The excess of antiprotons (P) observed in cosmic rays has been attributed to their production in supernova envelopes expanding in dense clouds. While creating P, γ-rays are also produced and these clouds would shine as γ-rays sources. The evolution of the γ-ray spectrum has been calculated for clouds of nH = 104 and 105atom/cm3.
