The electron distribution with respect to transverse energy is derived for electron cyclotron resonance in a constant, homogeneous magnetic field; weak relativistic effects are taken into account. After the establishment of a steady-state distribution with groups of hot and cold electrons, no energy is pumped from the rf field to the plasma. The rf electrostatic perturbations are studied on the basis of the distribution function found; it is shown that waves of two types are unstable eigenmodes of the plasma at rest and drift waves. The growth rates for the corresponding instabilities are derived. A study is also made of the stability of right-handed circularly polarized electromagnetic wave propagating along the magnetic field. Instabilities occur at frequencies which depend on the degree of anisotropy, analogous to the case of a plasma with a temperature anisotropy.
