Abstract
We present a theory of magneto-oscillations around the ν=1/2 Landau level filling factor based on a model with a fluctuating Chern-Simons field. The quasiclassical treatment of the problem is appropriate and leads to an unconventional exp[-(π/] behavior of the amplitude of oscillations. This result is in good qualitative agreement with available experimental data, although the experimental value of exceeds considerably our theoretical estimate.
