Solar Maximum Mission data on the times of occurrence of the microwave, hard X-ray, and gamma ray emissions from the solar flares of June 7 and 21, 1980, were analyzed for the acceleration mechanisms. Seven consecutive pulses were detected from the June 7 event, with all emissions present nearly simultaneously, while the June 21 flare exhibited four pulsations with similar relative timing. The gamma ray peak lagged several seconds behind the X-ray burst. Microwave emissions displayed two subpeaks in both cases, with the X-ray emissions weakening during the second subpeak. Possible acceleration mechanisms, the same or different for the X-ray and gamma ray lines, are discussed, noting that an electron density of 5 x 10 to the 12th/cu cm is necessary for the gamma rays to lag the X-rays if the cause lies in differences in either the transit or relaxation times for the electrons and the ions.
