Abstract

The results of the precise measurement of the refractive index of stable germanium isotopes ${}^{72}{Ge}$ , ${}^{73}{Ge}$ , ${}^{74}{Ge}$ , and ${}^{76}{Ge}$ single crystals with high enrichment and a germanium single-crystal ${}^{nat}{Ge}$ of natural isotopic composition with the Fourier-transform interference refractometry method from 1.94 to 20 μm with $0.1 {cm}^{- 1}$ resolution and accuracy of $2 \times 10^{- 5}$ to $1 \times 10^{- 4}$ are shown. The content of 72 impurities measured by the mass spectrometric method was below $10^{- 5} - 10^{- 6}$ wt. %. Oxygen and carbon concentrations measured by IR spectroscopy in all crystals are within $5 \times 10^{15} {cm}^{- 3}$ . All germanium crystals have a hole conductivity with specific electric resistivity of $45 - 50 Ohm \times cm$ . The coefficients of the generalized Cauchy dispersion function approximating the experimental refractive index values all over the measuring range are given. The transmission and Raman spectra are also given.
