Nonlinear production of suprathermal tails in auroral electronsNew rocket data on auroral electron energy spectra are presented. Two regions of the aurora are sharply defined: the peak energy region, called the beam, and a strongly altitude-dependent tail of slowed-down secondary and backscattered electrons. It is shown that the oscillating two-stream instability described by Papadopoulos and Coffey (1974) accounts for the observed features of the tail.
