Abstract
The energy splittings of the lithiumlike ions , , and have been measured at the Experimental Storage Ring, utilizing low energy dielectronic recombination. The resonance energies in total 41 different () autoionizing Rydberg states populated in the dielectronic capture process have been determined. The excitation energies have been obtained by extrapolation of these resonance energies to the associated series limits . The combined analysis of the experimental data for all three ions yields for , 230.650(81) eV for , and 280.516(99) eV for .
