Some characteristics of microwave type IV radio bursts and the acceleration of solar cosmic rays

This paper discusses the relationships between some characteristics of microwave type IV radio bursts and solar cosmic ray protons of MeV energy. It is shown that the peak flux intensity of those bursts is almost linearly correlated with the MeV proton peak flux observed by satellites near the earth. The rise times of type IV microwave emissions are, however, independent of the proton peak fluxes. Using these results, discussion is given on the acceleration process and duration for both protons and electrons. Key words: solar radio activity - solar cosmic rays
