无序取代合金中电子态密度的相干势近似被详细应用于松饼罐势系统。所有表达式都是根据各个原子散射体的相移来制定的。讨论了一个简单的例子，说明了一个紧束缚系统，其中纯成分具有不同的带宽。
The coherent potential approximation for the electronic density of states in a disordered substitutional alloy is applied in detail to a system of muffin-tin potentials. All expressions are formulated in terms of the phase shifts of the individual atomic scatterers. A simple example, illustrating a tight-binding system in which the pure constituents have different bandwidths, is discussed.
