Abstract

We show that in the case of generalized loss-cone distribution functions characterized by loss-cone index l, parallel thermal velocity α∥ and perpendicular spread α⊥ sufficiently large anisotropy, (α∥/α⊥), may stabilize the high-frequency electrostatic ion cyclotron instability. The discussion refers to the oblique propagation and includes also a second, cold, ion component (besides warm isotropic electrons). Electromagnetic corrections to the quasi-electrostatic dispersion relation are also considered. Simple analytical expressions for the growth rates are derived and discussed.
