Theoretical study on dielectronic satellites to the highly charged Nelike Eu resonance lines

Abstract

On the basis of the calculated wavelengths and intensities of n=3→2 transition in Nelike,Nalike and Mglike ions of Eu,and by considering the broadening of individual lines and overlapping of a large number of lines in plasma,we have simulated the spectral structure of n=3→2 resonance transition in Nelike ions and all of the dielectronic satellites transitions of Nalike and Mglike ions of Eu.Also the contributions from highn dielectronic satellites to the resonance line is considered and calculated.Compared with a few existing experimental results,the dielectronic satellite wavelength of 3s—2p transition shows a good agreement with experimental result.
