Sum of the Fermi level referenced (see Fermi level referencing) kinetic energy of a narrow Auger electron peak in the spectrum and the binding energy of the most intense photoelectron peak from the same element.
Note: The modified Auger parameter is the sum of the Auger parameter and the energy of the X-rays responsible for the measured photoelectron peak. Unlike the Auger parameter, it does not depend on the energy of the X-rays.
