WebThe cross sections for the production of 16 lines of the Zn(II), Cd(II), and Hg(II) spectra by ionization‐excitation collisions between electrons and neutral atoms have been measured over the energy range0–260eV. The spectral lines are characterized by optical excitation functions which reach their maximum values within the energy range 40–90 eV, and by … Webelements they can measure. Because the lamp must be changed between each element of interest, FAAS (and FAES) techniques analyze a single element at a time and are unable to easily analyze metalloids. ICP optical systems, by contrast, can analyze about 60 different elements at the same time with a single source (the plasma). how does optum pay workWebA program of research towards the high-resolution optical spectroscopy of actinide elements for the study of fundamental nuclear structure is currently ongoing at the IGISOL facility of the University of Jyväskylä.
