摘要：

A highly accurate measurement of Delta n = 0 dielectronic recombination (DR) resonances with Ar15+ has been carried out at the ion storage ring CRYRING. The absolute energies of the DR resonances were determined by a method that uses the Schottky frequency and the knowledge of the length of the beam orbit in the ring. The accuracy in the absolute energy achieved in this experiment was similar to 1%. Positions and widths of doubly excited states of Ar14+, as well as the DR cross sections, were calculated with relativistic many-body perturbation theory in an all-order formulation. Radiative corrections and mass polarization were needed to obtain good agreement with the experimental results.
