The optical properties of evaporated gold in the vacuum ultraviolet from 300 Å to 2 000 Å

Abstract
The reflectance and optical constants of evaporated gold films were measured in the vacuum ultraviolet from 300 Å to 2 000 Å. The optical constants were determined from reflectance measurements made at various angles of incidence. In contrast to aluminium, gold shows little change in reflectance after deposition in vacuum and during exposure to air. Due to interference, semitransparent films of about 150 Å on glass show the highest reflectance at most wavelengths in the vacuum ultraviolet
