摘要：
A new method of detecting low-frequency ion-sound turbulence in solar chromospheric flares is proposed. The method is based on analysis of the hydrogen Paschen γ line profiles, which exhibit-under the appropriate conditions-diagnostically important humps in the line wings around Δλ {reversed tilde equals} 1 Å. We discuss the problem of Paschen γ line formation under the influence of low-frequency turbulent electric fields and compare our theoretical results with recent spectral observations. From comparison with the observed profile, we derive a turbulent electric field mean intensity of F0 {reversed tilde equals} 3 CGS. © 1990.
