Sources Of The High-energy Tail Of Solar Wind

The heliosphere is filled with hot dilute plasma known as solar wind. Due to thermal collisions, the velocity distribution of ions follows a Maxwell distribution. The measured energy spectrum of the ions above the peak at about 1 keV/nucleon, however, is not falling off as rapidly as the Maxwell distribution would predict. Instead, the spectrum
