The line strengths of 2–2 and 3–3 transitions (2 s 2 2 p 5 3 s –2 s 2 2 p 5 3 p –2 s 2 2 p 5 3 d , 2 s 2 s 2 p 6 3 s –2 s 2 p 6 3 p ‐2 s 2 p 6 3 d , 2 s 2 2 p 5 3 l ‐2 s 2 p 6 3 l ) have been calculated for the Ne isoelectronic sequence ( Z = 14 ÷ 100). The calculation has been carried out in intermediate coupling. Relativistic corrections have been included through the Breit operator. Perturbation theory in 1/ Z has been used to account for electronic interactions.
