COS-B gamma-ray measurements, cosmic rays and the local interstellar medium
Abstract
The results of COS-B gamma ray, cosmic ray, and the local interstellar medium measurements are summarized, with particular regard for H I emissions at galactic longitude 240 deg. Significant quantities of atomic hydrogen are calculated from the local gamma ray emissivity, and the gamma ray emissivity spectrum is deconvolved from equations of the expected number of photons in the ranges 70-150 and 150-300 MeV. The intermediate latitude structure over the longitude range is closely related to the Gould and Dolidze belts, and data is presented for H I emissions in the 70-5000 MeV range. Large column densities of H2 are concluded from the gamma ray excesses relative to the atomic hydrogen contribution in longitudes 300-360 deg.
