A Note on the Position of Peaks of Kα₁ and Kα₂ Doublet

Abstract

Four functions are assumed for the intensity distribution curves of the lines of Kα₁ and Kα₂ rays. The apparent positions of the curves obtained by superimposing two curves corresponding α₁ and α₂ are calculated numerically, and the shift of peaks as a function of half-peak breadth are shown in a figure. As the breadths increase the peaks shift with respective rates towards an ultimate position that is the center of gravity of intensity of the doublet lines, however, it is not the case for asymmetrical lines and for lines having an inflexion at the peak.
