摘要：

We present a theory of magneto-oscillations around the v=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 unconventioal exp -(pi/omega(c)tau(1/2)(*))(4) behavior of the amplitude of oscillations. This result is in good qualitative agreement with available experimental data, although the experimental value of tau(1/2)(*) exceeds considerably our theoretical estimate.
