Abstract : A new class of collisiondependent electron waves is found in a nonMaxwellian Lorentz magnetoplasma, and it is shown that these waves may be driven unstable by electronneutral collisions. The Boltzmann equation with collision integral is solved, assuming propagation either parallel or perpendicular to the magnetic field. Both conductivity tensors are derived and put in a form useful for numerical calculations. The full set of Maxwell's equations is then used to derive the dispersion relations for both directions of propagation. The dispersion relations are initially solved for a monoenergetic electron distribution function and following that a distribution with a peak of nonzero halfwidth is treated. Some consideration is also given to a Maxwellian distribution both with and without a bump on the tail. As an example of propagation parallel to the magnetic field, transverse electromagnetic or whistler waves are considered. (Author)
