Abstract A strong enhancement of electron-ion recombination over expected rates at sub-eV relative energies is revealed for highly charged ions. Measured Ne{sup 10+} and Ar{sup 13+} recombination rates were found to be enhanced at low ({lt}1 meV) energies by factors of 4 and 10 over theoretical predictions of radiative recombination rates, respectively. It is shown that the majority of the enhancement in Ar{sup 13+} is caused by very low lying {Delta}{ital n}=0 dielectronic recombination resonances; nevertheless, the nonresonant contributions to the measured recombination rates for both systems were found to be significantly higher than predicted by presently available models. {copyright} {ital 1995 The American Physical Society.}
