Origin of the satellite observed on the high energy side of Lγ2,3 diagram lines

Abstract

On the high energy side of the unresolved doublet Lγ23in the L spectra of some elements, a satellite Lγ2,3' has been reported in literature, which has been ascribed to the transition L1Mx − MxN2,3, on the basis of energy considerations alone, by earlier workers. In the present work, apart from energy, calculations have also been done for the intensity of the probable transitions which may give rise to the satellite in the elements from 40Zr to 47Ag and from 57La to 63Eu. Firstly, the probability of creation of a single hole K state has been calculated. Double hole state L1Mx is created by Coster-Kronig transitions (K − L1Mx) as well as by shake off process. The probabilities of these two processes have been calculated. The total probability of creation of the double hole state thus obtained has been statistically distributed among the 24 allowed transitions from the set of L1Mx levels. By taking each of the transitions as a Gaussian line, a composite spectrum has been computed. This theoretical spectrum has been compared with the available satellite energy data. The transitions which give rise to this satellite have thus been identified in the elements studied.
