Recently Edlen and:Tyren have reported the observation of groups of weak lines tojthe long wave length side of the lines 1s2 1S-1s2p 1P in the CV-like spectra, and the 18a S-2p'P in the CVI-like spectra of the light elements. These satellite lineg they ascribed to transitions in the respective preceding spectrum with an additional external électron whose effect of screening on the energy of transition giving rise to the main line is small. Thus the transition 18IS-182p S-282p 1P, 1s2s S-2s2p 3P, 282p 3P-2p 3P,132p1P-203 ID,1S,etc. The purpose of thig paper is to calculate the energies of the initial states involved in the emission of these satellite lines and to attempt an identification of the lines observed by Edlén and Tyrén.
