The effect of improved satellite line shapes on the argon He-beta spectral feature

Résumé

The effect of the interference term in the electron broadening of the Li-like satellites to the Ar He-beta line has been investigated in the standard Stark broadening theory. Although the interference term has negligible or small effect on satellite lines with spectator electrons in n=2 and n=3 shells, it shows significant narrowing for lines with n=4 spectator electrons. Nevertheless, the improved n=4 satellite line shape makes a small difference in the emergent intensity distribution of the composite spectral feature. Accordingly, this change in line shape does not affect previous diagnosis of plasma conditions in Ar-doped ICF implosion cores.
