Optical Properties and Electronic Characteristics of Cerium in the Condensed State

The results of investigating optical properties of metallic cerium in the liquid and solid fi lm state are presented. Optical constants were measured by the ellipsometric Beattie method in the range of 0.42–2.6 μm at ambient temperature. Based on the measured refractive indices and the absorption co...

Zusammenfassung:	The results of investigating optical properties of metallic cerium in the liquid and solid fi lm state are presented. Optical constants were measured by the ellipsometric Beattie method in the range of 0.42–2.6 μm at ambient temperature. Based on the measured refractive indices and the absorption coefficients, spectra of light conductivity σ, reflectivity R, and characteristic loss function Im ε –1 were calculated. Based on experimental measurements in the IR region, electronic characteristics of liquid cerium and its polycrystalline film and their correlation with electrical conductivity have been determined.
