Description

The x-ray spectra, corresponding to the electric quadrupole transitions L1-M4,5, have been calculated for all lanthanides. An investigation of the influence of an open 4fN shell on the main characteristics of spectra has been performed. Due to the validity of the ground term approximation, the concentration of lines on the high-energy side of maxima takes place. When the 4fN shell is filled partially (N < 7), the natural width of L1-M4 maximum exceeds the width of L1-M5 maximum; for the almost filled shell the opposite result is obtained. It is explained by the change of total momentum of the ground level of 4fN shell from the minimum value at N ≤ 2l + 1 to the maximum value at N > 2l + 1
