蒸发铝膜的光学和电子能量损失数据进行了严格的分析，并用于迭代，自洽的算法，代表了结合的Kramers-Kronig分析和半量子模型的应用。在200 μ m（6.2meV）~ 0.12nm（10 keV）的宽光谱范围内测定了铝的本征光学函数的新值。这些函数与Lee和Chang [Phys. Rev. B 49，2362（1994）]最近用直流电导率测量的计算一致，并且与从电子能量损失实验获得的峰位置和线宽都很好地一致。内部一致性的惯性和f-和规则的结果进行检查。
Optical and electron-energy-loss data for evaporated-aluminum films have been critically analyzed and used in an iterative, self-consistent algorithm that represents a combination of the Kramers-Kronig analysis and the semiquantum-model application. The novel values of the intrinsic optical functions of aluminum have been determined in a wide spectral range from 200 mu m (6.2 meV) to 0.12 nm (10 keV). These functions are in accordance with recent calculations by Lee and Chang [Phys. Rev. B 49, 2362 (1994)], with dc conductivity measurements, and are in good agreement with both peak positions and line widths obtained from electron-energy-loss experiments. The results are examined for internal consistency by inertial and f-sum rules.
