WebChoice of X-ray Target. The wavelength, λ, of the characteristic line giving rise to a particular transition is given by Moseley's Law: 1 / λ = c (Z - σ) 2 where c and σ are constants, and Z is the atomic number of the metal used for the anode. From this equation it can seen that as the atomic number of the target increases, then the wavelength of the … WebX-ray Source Technology is a Key Competence of Bruker AXS.

WebX-ray diffraction (XRD) patterns of the catalysts were obtained with a RINT2000 wide angle goniometer 185 using Cu Ka radiation at 40 kV and 30 mA. X-ray photoelectron spectroscopy (XPS) analysis of the catalysts was performed on an ESCALAB 250 induced electron emission spectrometer with Al Kα(1486.6. eV, 12 mA, 20 kV) X-ray sources. WebThe photograph shows the typical metals used to filter X-rays produced by a sealed X-ray tube, i.e. Ni, Fe, Mn, V, or Zr. Filters preferentially reduce the intensity of the Kβ line in the X-ray spectrum compared to Kα as explained below.

K-alpha emission lines result when an electron transitions to a vacancy in the innermost "K" shell (principal quantum number n = 1) from a p orbital of the second, "L" shell (n = 2), leaving a vacancy there. By posing that initially in the K shell there is a single vacancy (and, hence, a single electron is already there), as well as that the L shell is not entirely empt…
