The authors report the spectrum of background events that theCOMPTEL instrument on Compton Gamma Ray Observatory experiences due tothe instantaneous effects of cosmic rays. Other backgrounds are presentin the data of this Compton telescope, but the components that closelyfollow the instantaneous flux of cosmic rays are the most identifiable.The background varies approximately linearly with the cosmic-rayintensity and exhibits a broad feature from about 1 to 10 MeV suggestiveof the nuclear nature of the events. Above 10 MeV there is a markedchange in the nature of the background that is not understood. Itappears that the background changes from nuclear to electromagnetic innature
