电子态密度函数计算的随机替代合金系统银-钯在整个浓度范围内的组合物的数量。计算是基于相干势近似。由于Ag-Pd体系的晶格常数对组成有较强的依赖性，因此有必要扩展以前用于描述Cu-Ni合金的简单模型哈密顿方法。计算结果与已发表的光电子能谱、光吸收谱、低温比热和泡利自旋磁化率实验结果一致。讨论了该合金体系中s-d电荷转移的可能性。
Electronic densities of states functions are calculated for the random substitutional alloy system Ag-Pd for a number of compositions across the complete range of concentrations. The calculations are based on the coherent potential approximation. It was found necessary to extend the simple model Hamiltonian method previously used to describe Cu-Ni alloys because of the stronger dependence of the lattice constant on composition in the Ag-Pd system. It is shown that the results are consistent with published photoemission and optical absorption data, and low temperature specific heat and Pauli spin susceptibility experiments. The possibility of s-d charge transfer in this alloy system is discussed.
