The use of N ( E ) = N FE k (∂ E ( k )/∂ k ) −1 as the electronic density of states for disordered metallic systems is critically examined. The present examination shows that its use is reasonable and that the applicability of the nearly‐free‐electron theory to the binary alloys of simple metals becomes worse and worse in going from the case of small charge transfer to the case of large charge transfer.
