The satellite spectra arising due to L3Mx±MxN4,5 (x =1-5) transition array in X-ray emission spectra of 74W, 76Os, 78Pt, 80Hg, 82Pb, 88Ra and 90Th, have been calculated using available HFS data on K±LM and L±MN Auger transition energies. The agreement between the calculated and measured energies, that between calculated and measured separations in energies and the consideration of the relative probabilities of all the L3Mx±MxN4,5 transitions have been used as the basis for deciding the origin of the satellites. It has been established that two satellites observed in the Lb2 region of the X-ray spectra of various elements and named b2 I and b2 II in order of increasing energy are mainly emitted by L3M4,5±M4,5N4,5 transitions. It is observed that the satellite b2 I in the spectra of elements with Z 74±76 has been assigned to the superposition of 3F4±3G5 and 3F4±3D3 transitions and that it must be the most intense of all these satellites. The same transitions have been proved to be the main origin of the satellite, b2II, reported in the range Z 78±90: Further, the satellite b2 I , reported in the spectra of elements with Z = 74W to 76Os, has been associated with the transitions 3D3±3F4 and 1D2±1F3. Finally, the line b2 II, reported in the spectra of elements Z = 74±76; has been assigned to the 1F3±1G4 transition. The possible contributions of other transitions of the L3Mx±MxN4,5 (x =1-5) array having intensities comparable with the above transitions, and the corresponding lines, which have not yet been observed, have also been discussed.
