Abstract
The Krall-Book model of ion-acoustic instability in an inhomogeneous plasma is extended to include the anisotropic effects in the plasma. It is found that whereas a greater thermal motion parallel to the magnetic field enhances the instability, a greater thermal motion perpendicular to the magnetic field reduces it.
