Abstract

The Lu–Fano graphical technique has been applied to the analysis of the strongly interacting J = 2 and J = 3 Rydberg levels of Si i which arise from the 3pnd configurations. Approximately 20 new J = 3 and 40 new J = 2 energy levels are reported. A periodic intensity variation in the ¹D₂–3pnd J = 3 transitions is discussed. Twenty-three new 3pnd¹P°₁ levels are reported.
