Abstract: The relationships of solar gamma ray (GR) emissions with microwave (MW) and other radio bursts have been studied. The GR emissions are found to start about 1-2 min after the onset of MW emissions (on 17 GHz) or about 0.5 min before the peak of MW emissions. The time delay may be due to differences in acceleration times for accelerating the electrons for MW emissions and protons, ions and nuclei for gamma ray (also line) emissions. Further, the GR emission flares are found to be associated fairly well with type-II and type-IV radio bursts while the gamma ray line (GRL) emission flares show higher association with the type-II and type-IV radio bursts. The type-II bursts start about 6 min after the onset of GR emissions while the type-IV bursts start about 2 min before the onset of GR emissions, which show that the GR emissions and the type-II (also type-IV) may not be produced simultaneously by shock waves.
