Abstract
The origin of the widely observed enhancement of rates for electron-ion rec ombination at very low energies is still unknown. We investigated the recom bination of Au25+ With free electrons in a merged-beams experiment at the U NILAC accelerator of the GSI in Darmstadt. At E-rel = 0 eV we found an enor mous enhancement factor of 365 compared to the theory of radiative recombin ation. An increase of the electron density by a factor of 10 had not much i nfluence on the measured rate coefficient.
