Аннотация:
The optical constants of Ni<sub>3</sub>Al from 0.5 to 53 eV have been determined by means of spectroscopic ellipsometry at room temperature under ultra-high vacuum conditions. Measurements were performed on a single crystal and a polycrystalline sample, which gave identical results. The results are compared with optical properties calculated from the band-structure calculation by Buiting et al. (1983). The experimental results are in good agreement with the predictions from the band-structure calculation.
