Abstract

A systematic experimental and theoretical study of doubly excited ls21nl’ states of three-electron ions has been performed. Theoretically the truncated diagonalization method (TDM) has been used to generate both non-relativistic and relativistic energy values, wave functions and quantum defects for 42 different Rydberg series converging to four different thresholds, i.e. (ls2s)3Se, 1Se and (ls2p)3P°, 1P°. This comprehensive data base has been used to classify recent high resolution Auger electron spectra arising from Li-like states. Specifically we have analyzed He-, C3+, O5+ and Ne7+ Auger electron data produced by double electron capture in slow ion-atom collisions. Numerous new lines associated with (ls21nl’) Rydberg levels have been identified.
