Copyright 2006 Casa Software Ltd. peak Fitting in XPS Small and sometimes not so small differences between the initial and final state of an atom when a core level electron is excited by an x-ray is fundamental to XPS as an analytical technique. These variations in the initial and final state energy are due to the environment in which an atom is found and results in electrons ejected from the same element emerging with kinetic energy characteristic of the chemical state in which the element exists. In terms of an XPS spectrum, the increase in counts as a function of kinetic energy associated with the excitation of a core level electron appears as an ensemble of peaks rather than a single peak .
