DEPENDENCE OF THE POSITION OF PHONON IR ABSORPTION BANDS OF GERMANIUM ISOTOPES ON THEIR MASS NUMBER

Abstract

For the first time, in a single experiment, the dependence of the position of the phonon absorption peaks in the IR spectrum (range 11–40 μm) for all five stable monoisotopic germanium single crystals was studied. The dependence obtained can be used to study the mass composition of germanium of various isotopic purity.
