Abstract

The gamma-ray emissivity for the narrow component (FWHM = 2°) at the 0.3–5 GeV range is derived as a function of the galactocentric distance. The narrow component might result from the interaction between cosmic rays and H2 gas. The mass of gas in the Galactic Center is not large enough to produce the gamma-ray peak, but enough to produce the far-infrared peak. The relation of far-infrared dip and near-infrared hump near l = 356° to gamma-ray hump is discussed.
