我们给出了顺磁性CuNi合金的复合能带和电子态密度。的计算是基于使用的平均$t$-矩阵近似的框架内的松饼罐潜力。该理论合理地预测了电子光谱在很宽的范围内的能量和合金成分。要讨论的实验包括光电子能谱测量的状态密度和丁格尔温度测量的颈部和腹部轨道的阻尼。详细讨论了富铜CuNi合金中Ni虚束缚态的半宽。
We present the complex energy bands and electronic densities of states in paramagnetic CuNi alloys. The calculations are based on the use of muffin-tin potentials within the framework of the average-$t$-matrix approximation. The theory is shown to predict reasonably the electronic spectrum over a wide range of energies and alloy compositions. The experiments to be discussed include photoemission measurements of the density of states and Dingle-temperature measurements of the damping of both the neck and belly orbits. The half-width of the Ni virtual bound state in Cu-rich CuNi alloys is discussed in detail.
