【 摘 要 】

We will show in this work that there is a possibility of unstable motion when the ion wind force on the particle is sufficiently strong. Since the ion wind force is predominately a decreasing function of the relative velocity of the ions and the particle, this can lead to unstable oscillatory motion. Potentially, this would appear to be an almost universal phenomenon for plasma dust particles.
