Energy-Dispersive X-Ray Emission Spectroscopy
Applied Spectroscopy, 1970A review is given of recent developments in energy-dispersive x-ray emission spectroscopy, with the aim of providing both an introductory and usefully practical look at this innovative field. The review begins with the first principles of x-ray production and observation, including a brief comparison of the performance capabilities of different types ...

Journal of Quantitative Spectroscopy and Radiative Transfer, 1994
Abstract Two groups of advanced spectroscopic instruments are described. The monolithic-crystal spectrometer and the vertical dispersion variant of the double-crystal spectrometer utilize the diffraction of x-rays from two mutually precisely-positioned crystal plates.

Valence to Core X‐ray Emission Spectroscopy
Advanced Materials, 2014This Progress Report discusses the chemical sensitivity of Kβ valence to core X‐ray emission spectroscopy (vtc‐XES) and its applications for investigating 3d‐transition‐metal based materials. Vtc‐XES can be used for ligand identification and for the characterization of the valence electronic levels. The technique provides information that is similar to

Electronic structure of In2O3 from resonant x-ray emission spectroscopy
Applied Physics Letters, 2009 The valence and conduction band structures of In2 O3 have been measured using a combination of valence band x-ray photoemission spectroscopy, O K -edge resonant x-ray emission spectroscopy, and O K -edge x-ray absorption spectroscopy. Excellent agreement

Polarized X-ray emission spectroscopy
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1989Abstract Strongly polarized X-ray fluorescence from gas-phase molecules has been observed by selectively exciting near core-level ionization thresholds using monochromatized synchrotron radiation. Both the degree and the direction of the polarization are very sensitive to the incident excitation energy, and the symmetry of the occupied and unoccupied

X-ray- and electron-induced infrared emission spectroscopy
Review of Scientific Instruments, 2009We demonstrate the use of Fourier transform infrared (IR) spectroscopy for midinfrared emission measurements following x-ray or electron excitation. Spectra from an InAs low band-gap semiconductor film, which emits in the IR from 3000 to 3400 cm−1, are presented. There is good agreement between the present results and previously published laser-excited

Resonant X-Ray Emission Spectroscopy of Molecular Oxygen
Physical Review Letters, 1996Resonant soft x-ray emission spectroscopy has been applied to study the issue of symmetry breaking upon core-hole excitation in molecular oxygen. The results provide direct evidence that the inversion symmetry is not broken in the core-excited states.

X-ray emission spectroscopy—part I
Contemporary Physics, 1973Abstract Summary of Part II: X-ray emission spectroscopy can detect several elements simultaneously in very low concentrations, and can be applied to many practical problems. Some applications in industry, in sir and water pollution by heavy metals, and in the study of the importance of trace elements in biology and medicine are discussed.

X-ray Emission Spectroscopy of Nitrogen-Rich Compounds
The Journal of Physical Chemistry A, 2011Nonresonant X-ray emission spectroscopy was used to compare the nitrogen-rich compounds ammonium nitrate, trinitrotoluene, and cyclotrimethylene-trinitramine. They are representative of crystalline and molecular structures of special importance in industrial and military applications. The spectral signature of each substance was analyzed and correlated

X-ray Spectroscopy of the Scattered Emission in NGC 1068
Astrophysics and Space Science, 1997We discuss the iron K line complex in NGC 1068. The line complex basically consists of three components, as previously reported. A new analysis of the ASCA data shows that cold reflection appears to dominate the observed X-ray emission above 4 keV based on the detection of ‘Compton shoulder’, a weak red wing of the 6.4 keV fluorescence iron K line, and
