Helmken, H. F. ; Weekes, T. C. Abstract Regions of the sky surrounding nine of the 100 MeV y-ray sources reported by the SAS 2 and Cos B satellite experiments have been examined for very high energy (100-1000 0eV) 7-ray emission using the atmospheric Cerenkov technique. Included in the search list were CO 195+4, CO 135+1, and CO 78+1. The absence of statistically significant fluxes places new upper limits on the high-energy 7-ray emission and implies a steepening of the source spectrum between 100 MeV and 2000eV.
