AN EXPERIMENTAL STUDY OF THE OPTICAL PROPERTIES OF LIQUID HG AND LIQUID GA IN THE WAVELENGTH RANGE OF 0.23µ TO 13µ

摘要

Methods previously developed for studying the optical properties of solid metals were modified to permit their use for studying liquid Hg and liquid Ga. Reflectivities were measured at an angle of incidence of 45°at glass-metal, quartz-metal, and NaCl-metal interfaces in the wavelength rage of 0.23μ to 13μ. Ina second type of experiment the phase change accompanying reflection at normal incidence at a mica-metal interface was measured in the range 0.4μ to 0.87μ.nThe values thus obtained agreed to within the experimental accuracy with those calculated with the Drude free electron theory.
