Abstract

A large part of the diffuse gamma-ray background may be attributed to inverse Compton scattering in the Galactic halo. Consideration is given to electrons injected from the disk which diffuse with mean free paths of 2 pc and 20 pc respectively. The larger value is required to give a fit to observations at 100 MeV. The predicted anisotropy is high and will provide an observational test in the future.
