X-ray photoelectron spectroscopy (XPS) is a technique for analyzing the surface chemistry of a material. XPS can measure the elemental composition, empirical formula, chemical state and electronic state of the elements within a material. XPS spectra are obtained by irradiating a solid surface with ...
X-ray spectracross-sectionchemical effectProposed single molecule surface-enhanced Raman scattering (SM-SERS) mechanisms are discussed and problems in SM-SERS of biological molecules are pointed out. It is unlikely that the single molecule signals can be explained exclusively by electromagnetic (EM) '...
What is the difference between emission and absorption spectra? Hospital X-ray generators emit X-rays with wavelengths of about 15.0 nanometers (nm), where 1 nm = 10-9 m. What is the energy of a photon of the X-rays? Which of the following statements is true? Explain your choice...
Energy Dispersive X-ray Spectrometry (EDXS) is the routine technique for determining the elemental makeup and composition of materials in the Scanning or Transmission Electron Microscope (SEM/TEM). EDXS is almost always shortened, and the technique is mo
Interpretation of XRF spectra Most atoms have several electron orbitals (K shell, L shell, M shell, for example). When X-ray energy causes electrons to transfer in and out of these shell levels, XRF peaks with varying intensities are created and will be present in the spectrum, a graphical...
What is X-ray astronomy used for? What wavelengths of light are used for an infrared telescope? What space telescope detects infrared light from objects? What is observational astrophysics? What is ancient astronomy? What technology was used in the Hubble Telescope?

we have postponed the discussion of X-rays until the present chapter because it is particularly convenient to treat X-ray spectra after treating optical spectra. Although this ordering may have given the reader a distorted impression of the historical importance of X-rays, this impression will be...

Both solar wind charge exchange emission and diffuse thermal emission from the Local Bubble are strongly dominated in the soft X-ray band by lines from highly ionized elements. While both processes share many of the same lines, the spectra should differ significantly due to the different production...
