Abstract: The satellite spectra arising due to L3Mx-MxN4.5 (x= 1-5) transition array in X-ray emission spectra of 75Re, 77 Ir and 79Au, have been calculated, using available Hartree-Fock-Slater (HFS) data on K-LM and L-MN Auger transition energies. The agreement between the calculated and measured energies, between calculated and measured separations in energies and the consideration of the relative probabilities of all the L3M,-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 Lβ2 region of the X-ray spectra of the elements with Z=75 to 79, named β21and β2II in order of increasing energy are mainly emitted by L3M4.5-M4.5N4.5 transitions. The satellite β21 has been assigned to the super-position of the transitions 3F4- 3G5 and 3F4- 3D3, contributing in order of decreasing intensity, and the line β2II, has been assigned to mainly the 1F3-1G4 and 3P0-3D1 transitions. The possible contributions of other transitions of the L3Mx-MxN4.5 (x1-5) array having appreciable intensities have also been discussed.
