Stability of the mid-latitude ionospheric plasma when photoelectrons are present in it

Inner magnetospheric superthermal electron transport: Photoelectron and plasma sheet electron sources

“…Choosing a AE of much less than 1 eV is necessary to accurately resolve each peak [cf. Jasperse and Smith, 1978], and the stability of these peaks have been debated as a source of plasma waves [Butvin et al, 1975;Kudryashev et al, 1979;Ivanov et al, 1980Ivanov et al, , 1982. Because we are focusing on the global formation and evolution of the distribution function rather than the possible instabilities, a reasonably large energy step was chosen.…”
