Electron excited M‐emission spectra of some heavy elements (64 ≦ Z ≦ 92) were studied by means of energy dispersive X‐ray spectrometry. Large discrepancies to literature data where found for the relative intensity of the Mζ‐line which is usually the strongest of the weak M‐lines. For elements Z ≧ 71 the relative intensity is almost constant and amounts to about 5%. In case of the rare earth elements Gd and Dy higher values of about 20% were obtained which are caused by anomalous self‐absorption effects for Mα and Mβ. These are reflected, too, by unusual high relative intensities of the lines Mγ and M 2 N 4 . The energy of the lutetium Mγ‐line was determined to be (1230.4 ± 0.3) eV.
