LET X-RAY-EMISSION SPECTRA OF GE GEO2 GAP GAAS AND GA2O3

With a high-resolution two-crystal vacuum spectrometer equipped with b eryl crystals, the Ge L alpha emission and Ga L alpha emission spectra in fluorescence have been measured for Ge, GeO2, GaP, GaAs and Ga2O3. The measured L alpha emission spectra consist of a prominent peak L a lpha(1,2) and its high-energy structure, and are slightly influenced b y chemical bonding. The L alpha emission spectrum of Ge is compared wi th available multiplet calculations for Ge L alpha(1,2) satellites. Th e high-energy structure is primarily attributed to the satellites as a result of multiple ionizations.
