| Research Abstract |
We tried to develop a high-performance X-ray spectrometer that enables us to measure X-ray Raman scattering spectra in laboratory. A prototype spectrometer was constructed, investigated, and updated over three years. In the tuning process, a solid state detector was introduced, making it possible to measure X-ray emission spectra both in wavelength-dispersion mode and energy-dispersion mode. The achieved energy resolution was markedly high, i.e., < 0.5 eV. In spite of these interesting properties of the spectrometer, it is still difficult to elucidate X-ray absorption fine structures from the measured X-ray Raman scattering spectra, mainly because of fairly low reflectivity of the analyzing crystals employed. Such difficulties forced us to apply the prototype spectrometer to the studies of other weak X-ray emission spectra. As a result, new chemical effects of L emissions of Sm and Yb were found.
