The kinetic energy of the primary ion should be in which of the following range?(a) 0.1-4 keV(b) 0.2-1 keV(c) 0.4-2 keV(d) 0.3-5 keVThis question was posed to me in an online interview.This intriguing question comes from Ion Spectroscopy in section Electron and Ion Spectrometers of Analytical Instrumentation

Answer»

Right choice is (d) 0.3-5 keV

To explain: The kinetic energy of the primary ion should be 0.3-5 keV. These primary ions are MADE INCIDENT on the SURFACE.
