摘要：

We report experiments on resonant tunneling through a quantum antidot in fractional quantum Hall regime. The envelope of the conductance peaks indicates tunneling via two resonant states, one of them bound on the lithographic antidot, the other on a hill of disorder potential. Moreover, our analysis indicates large coherent coupling between the two states, thus giving evidence for an 'antidot molecule'. (C) 2000 Elsevier Science B.V. All rights reserved.
