Please select your desired series.



* The combined Kα1, Kα2 is used for Z less than 40. The Kα1 only is used for the higher Z values.

** The data set for the N-Series peaks is not completely characterized by standardized methods.

K-Series Relative Peak Intensities
18 <= Z < 59
100 %
10-20 %
At Z less than 18, the Kβ decreases in height, and becomes closer to, and is eventually not resolved from the Kα. At Z greater than 59, the Kβ increases in size and sub-peaks can be seen.

L-Series Relative Peak Intensities
21 <= Z <= 34 35 < Z
Ll 200-6 % 3.5-6 %
Ln 70-3 % 2-3 %
1 100 % 100 %
1 20-34 % 35-52 %
2 0 % 0-20 %
1 0 % 0-8 %
2 0 % 0-2 %
At Z less than 21, the Lα1 and Lβ1 are 0 and Ll is the dominant peak. The Ll is not observable at a Z of 14 or less.

M-Series Relative Peak Intensities
57 <= Z <= 70 70 < Z
Mz 140-13 % 6-4.5 %
100 % 100 %
0-45 % 45-57 %
20-3 % 3.5-1 %
M2N4 0-2 % 0-2 %
At Z less than 57, the Mα becomes 0% and the Mz is the dominant peak. The Mγ becomes 0 at Z < 50.
