| Abstract: | In the homogeneous model of solar radio burst model, the spectral index of the optically thick part of the spectrum is almost independent of the spectral index of the electron energy, while from the optically thin part, the derived electron index δR is far smaller than that derived from the X-ray emission, δX. An inhomogeneous model is proposed, in which, by adjusting two parameters within reasonable limits, we can make δR, derived from both the optically thick and thin parts, to equal δX. The model is exemplified by the 1981 April 27 0800 UT burst. |
