Abstract The energies and intensities of the various transitions corresponding to the transition scheme 2p 3/2 −1 3 x −1 –3 x −1 3d 3/2 −1 (i.e. L 3 M x –M x M 4 ) were used to compute theoretical Lα 2 satellite spectra in 13 elements in the atomic number range of 62 ≤ Z ≤ 90. The energies were calculated using available HFS data on K–LM and L–MM transition energies. The intensities of all the possible transitions were estimated by considering cross‐sections for the Auger transitions simultaneous to a hole creation and then distributing statistically the total cross‐sections for initial two‐hole states 2p 3/2 −1 3 x −1 (L 3 M x ) amongst various allowed transitions from these initial states to 3 x −1 3d 3/2 −1 (M x M 4 ) final states. Each transition was assumed to give rise to a Gaussian line and the overall spectrum was computed as the sum of these Gaussian curves. The calculated spectra were compared with the available measured Lα satellite spectra. The peaks in the theoretical satellite spectra were identified as the experimentally reported satellites Lα s , La 13 , La 14 and La 17 , which lie on the high‐energy side of the Lα 2 dipole line.
