Abstract
We consider the single-particle relaxation rate of 2D electrons subjec t to a random magnetic field. The density-of-states (DOS) oscillations in a uniform magnetic field (in addition to a random one) are studied . We define a gauge-invariant single-particle relaxation time as a par ameter describing the amplitude of DOS oscillations. Unlike the conven tional case of random potential scattering, the broadening of the Land au levels does not depend on magnetic field.
