Abstract
Oblique ion acoustic waves in a current-carrying, magnetized plasma ar e investigated. For a multi-ion plasma whose dominant components are h ydrogen and helium, it is found that for some plasma parameters, obliq ue ion acoustic waves can have positive growth rates at frequencies om ega congruent-to OMEGA(He-3) (He-3 cyclotron frequency) and, at the sa me time, negative growth rates at omega congruent-to OMEGA(He-3). It i s then suggested that these waves can play an essential role in He-3-r ich solar flares.
