Abstract: The reflection spectra of LiH and LiD single crystals cleaved in ultrahigh vacuum (2.8 $\times$ 10$^{-10}$ Torr) at a temperature of 8 K have been studied using synchrotron radiation in the 4–35 eV photon energy range. The electron structure of lithium hydride in the vacuum ultraviolet range is interpreted. A method of rapid determination of the isotope composition of mixed LiH$_x$–LiD$_{(1-x)}$ crystals is proposed that is based on the measurement of reflection spectra in the exciton range.
