The dielectronic recombination rate coefficients of and ions have been measured at a heavy-ion storage ring. The investigated energy ranges covered all dielectronic recombination resonances attached to () core excitations. The rate coefficients in a plasma were derived and parameterized by using a convenient fit formula. The experimentally derived rate coefficients were then compared to theoretical data. In addition the influence of external electric fields with field strengths up to 1300 V/cm on the dielectronic recombination rate coefficient was investigated.
