A mechanism for the injection of very low energy particles into the magnetosphere

A mechanism for the injection of very low energy particles into the magnetosphere is suggested. Protons in the solar plasma accelerate neutral hydrogen atoms in the interplanetary gas by charge exchange; these hydrogen atoms are stripped by the gas in the exosphere to give protons. The rate of such injection into the magnetosphere during a geomagnetic storm is calculated and is found to be about 1022 protons per second of energy ∼20 KeV.
