Abstract
The origin of the satellites Lα6 and Lα7 have been explained in the elements from 40Zr to 50Sn. The energies and the intensities of the various transitions corresponding to the L3Mx - MxM4,5 (where x = 1-5) transition array, which may give rise to these satellites, have been calculated theoretically. The transition energies have been calculated using the available Hartree-Fock-Slater data for K-LM and L-MM Auger transition energies. The intensities of the various transitions have been estimated by considering cross sections L1-L3MX for Coster- Kronig transitions as well as for M-shell shake-off process occurring simultaneous to a L3 hole creation. The total cross sections for initial two-hole states have been then distributed statistically amongst various allowed transitions from the initial states L3Mx to the final states MxM4,5. Each transition has been assumed to give rise to a Gaussian line and then the theoretical satellite spectrum has been computed by summing up these Gaussian lines. The calculated energies have been found to be comparable with the measured energies of the satellites Lα6 and Lα7. Consequently, the transitions which give rise to these satellites have been identified. The satellite Lag has been assigned the transition 3D2L3M3 - 3F3M3M5 and the satellite Lα7 the transition 3PqL3M3 - 3P1M3M5 in all the elements from 40Zr to 50Sn.
