Abstract. We consider fermions in a constant and uniform external SU(2) magnetic field. We find that the results for the energy levels depend on the choice of gauge. Choosing a Landau-type gauge yields results analagous to those of Abelian theories. On the other hand, using another gauge potential one obtains a different continuous eigenvalue spectrum.
