Diagnostics of Plasma Turbulence of Solar Flares from the Scattering of Flares Radio Emission by Plasmons
Scattering of low-frequency photons in turbulent plasma produces distortions of the initial emission spectrum. There are two characteristic frequencies ν1, ν2 on which these distortions occur. Estimations are made of the ν1, ν2 and of the bluring effects of the time and frequency fine structure for the four main regions of plasma turbulence in the solar flare. The observational data are pesented which show that scattering effects by plasmons occur, apparently, in the spectrum and time dynamics of microwave bursts and type IV bursts in the characteristics of type I bursts during the noise storms, and in the radio emission distribution of S-component over the solar disk.
