摘要：
The effect of short-range-potential scattering centers in two-dimensional quantum-mechanical systems with an applied magnetic field is considered. The effective interaction disappears in the limit of an ideal two-dimensional behavior and a vanishing spatial range of the potential. It is suggested that this result explains the observed field dependence of the energy gaps in the fractional quantum Hall effect, which is very different from that derived in the lowest-Landau-level approximation.
