Scientific paper

A possible interpretation of the injection of electrons and the correlation of hard X-ray and type III/V radio emission is presented. A possible model is also presented of the nonlinear excitation of ion sound fluctations from type III beams and the streaming of low-energy superthermal electrons inside a turbulent plasma. It is suggested that the high-energy electron stream, which generates type III bursts and the spiky X-ray component, excites intense plasma waves which nonlinearly drive ion density fluctuations. These fluctuations enhance the collision frequency of the streaming low-energy particles and force them to form a positive slope. This allows the 30 keV hot plasma to excite plasma waves in the same frequency range as type III bursts and to generate type V emission.
