Abstract / Description:The electron-ion recombination spectrum of the Li-like Na8+ ion in the energy range 0.0–0.5 eV is presented. Experimental results obtained by storage-ring techniques are compared with a calculated spectrum, based on a combination of relativistic many-body methods and complex rotation, and the agreement is found to be very good. The deviations between measured and calculated dielectronic recombination resonance energies are usually below about 2 meV with a maximum difference at 5.5 meV, while the theoretical cross sections deviate by at most 20% from the experiment. The recombination spectrum in the investigated energy region is determined by the 2pj7[script-l]j[prime] Rydberg manifold of dielectronic recombination resonances, comprising 61 states within half an eV above the ground state of Na8+. The theoretical resonance parameters of all contributing states are provided.
