✦ Synopsis

Two examples of clouds of narrowband din-spikes, observed by the Ondi~e,jov radiospeclrograph in the I. 2 GHz frequency range, arc analyzed. After transformation of the frequency scales to distances in the solar atmosphere, the power spectra analysis of size scales reveals a spectral index of-~, resembling that of Kohnogorov spectra of turbulent cascades. The narrowband din--spikes are interpreted as radio emission from electrons accelerated in MIlD cascading ~.aves, probably generated in plasma out[lows from magnetic lield reconnection.
