The alloy density of states calculated with a Monte‐Carlo technique is compared to that calculated with a small cluster approximation. It is shown that the use of small clusters imbedded in an effective medium can give rise to spurious structure in the density of states while the two methods give the same results in the limit of large clusters. The conditions are determined for localization in such systems and some conjectures concerning the nature of localized states observed in real liquid alloys are made.
