Abstract: 
Absolute rate coefficients for the dielectronic recombination (DR) of Na8+ ions producing doubly excited states in beryllium-like Na7- have been measured at the Heidelberg heavy-ion test storage ring (TSR). The investigated electron energy range covers all DR resonances related to 2s --> 2p(1/2) and 2s --> 2p(3/2) Deltan = 0 core excitations. Resonances related to Deltan = 1 and Deltan = 2 transitions of the valence electron are found at relative energies between 50 and 250 eV. At very low energies the resonance group associated with Na7+(1s(2)2p(j)7I(j')) intermediate states has been investigated with an energy resolution and precision that will challenge state-of-the-art theory.
