The linear Vlasov theory of the universal instability driven by a density gradient in a unidirectional magnetic field is considered in the slab model with the local approximation. The electrostatic approximation is used, but the full resonant effects of a magnetic field gradient drift are included for the ions. Both electron and ion delB effects reduce the growth rate, but the latter is more important. It is shown that the nonresonant ion delB approximation fails at relatively low ..beta.. and that the conventional resonant ion approximation becomes invalid as ..beta.. increases.
