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

The satellite spectra arising due to L3Mx-MxN4.5 (x = 1-5) transition array in X-ray emission spectra of Mo-42, Ru-44, Pd-46, Cd-48, Sn-50 and Te-52, have been calculated using available I-IFS 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 L beta(2) region of the X-ray spectra of various elements and named beta(2)((b)), beta(2)(II) and beta(2)((c)) in order of increasing energy are mainly emitted by L3M4.5-M4.5N4.5 transitions. It is observed that only beta(2)((b)) in all these spectra can be assigned to superposition of F-3(4)-(3)G(5) and F-3(4)-D-3(3) 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 beta(2)(I) which has been observed on lower energy side of beta(2)((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. (C) 2000 Elsevier Science Ltd. All rights reserved.
