THE DIFFERENCE IN LINE'S EXTREMUM LOCATION FOR VARIOUS REPRESENTATIONS

In the undiffrentiated spectrum the energetic position of the line is assumed to be the abscissa of its maximum. In the differentiated spectrum this maximum corresponds to zero of the line contour's derivative, but the energetic position is determined easier as an abscissa of the derivative's negative extremum. The negative extremum of the EBE line contour is a refernce point for the energy loss scale in the dN(E)/dE () mode. The minimum's position in the mode and the maximum's position in the N(E) mode coincide with each other, while positions of line contour extrema are different in the dN(E)/dE and N(E) modes.
