Transition assignments to Lβ2 satellites in X-ray emission spectra of middle-Z elements Original Research Article

The satellite spectra arising due to L3Mx–MxN4,5 (x=1–5) transition array in X-ray emission spectra of 42Mo, 44Ru, 46Pd, 48Cd, 50Sn and 52Te, 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 three satellites observed in the Lβ2 region of the X-ray spectra of various elements and named and β2(c) in order of increasing energy are mainly emitted by L3M4,5–M4,5N4,5 transitions. It is observed that only β2(b) in all these spectra can be assigned to superposition of 3F4–3G5 and 3F4–3D3 transitions and that this must be the most intense of all these satellites. Each of the remaining two satellites is found to have different origin in different elements. So is the case with the line β2I which has been observed on lower energy side of β2(b) and has been associated with an L3M4,5–M4,5N4,5 transition in some elements. The suitable transitions to all these lines have been presented.
