摘要：

We have observed a strongly non-Gaussian distribution of Coulomb blockade conductance peak heights for tunneling through quantum dots. At zero magnetic field, a low-conductance spike dominates the distribution; the distribution at nonzero field is distinctly different and still non-Gaussian. The observed distributions are consistent with theoretical predictions based on single-level tunneling and the concept of ''quantum chaos'' in a closed system weakly coupled to leads.
