The influence of collective effects on the nonthermal X-ray radiation from solar flares
Abstract
It is shown that the collective deceleration of nonthermal electrons in the electric field of a stable inverse current and the ionization of the upper layers of the chromosphere upon exposure to accelerated electrons can have a significant effect on the shape of the nonthermal X-ray radiation spectrum of solar flares. Radiation cooling stabilizes the temperature. The isotropization of accelerated electrons and the collision damping of Langmuir waves depress the beam instability.
