Abstract: 
Absolute cross sections for dielectronic recombination and electron-impact ionization of Li-like Cl14+ and Si11+ ions have been measured with high energy resolution at the Heidelberg heavy ion storage ring TSR, using the electron cooler as a flee electron target. Recombination and ionization rates were recorded simultaneously for the whole energy range from 0 up to the second ionization threshold. We discuss excitation-autoionization steps, dielectronic ionization and dielectronic recombination resonances associated with 1s --> 21 and Is --> 31 excitations. The results agree well with theory, but the distorted wave calculations overestimate direct ionization by similar to 20%.
