The high-frequency precessional mode of a hot-electron-stabilized magnetic configuration has previously been shown to be stable in a window of core-plasma mass. Under conditions of frequency matching, the resulting stable negative-energy precessional wave can be destabilized by coupling to positive-energy shear-Alfvén waves. Coupling is avoided when the hot-electron precession frequency exceeds the core-plasma ion gyrofrequency.
Baldwin et al. (1983) studied this question.
