摘要：

We have investigated anomalously localized states (ALS) at the critical point of the Anderson transition. Nonmultifractality of ALS has been characterized by F,? calculated from the correlation function of qth moments of coarse-grained sqaured amplitudes of wave functions. It is found that the distribution function of Gamma(q) becomes broad as increasing the system size. This behavior supports our previous results for q = 2, and enables us to conclude that ALS exist at the critical point even in the thermodynamic limit.
