Abstract: 
Recombination of Bi80+ ions with electrons at low relative energies has been investigated employing the electron cooler at the experimental storage ring of the Gesellschaft fur Schwerionenforschung in Darmstadt. Absolute recombination rate coefficients have been determined for relative energies E-rel between 1x10(-5) and 10 eV. Simulations of cooling-force effects were carried out to assure the validity of these energies. In the range 10 meV less than or similar toE(rel)less than or similar to 10 eV the measured rate coefficients agree well with the theory for radiative recombination (RR). Towards lower relative energies (E(rel)less than or similar to10 meV) the measured rate coefficients increasingly exceed the prediction of the RR theory. At the lowest accessible relative energy the ratio of measured and calculated rates reaches a factor of 3.5. The enhancement is found insensitive to a variation of the electron density from 1.6x10(6) to 4.8x10(6) cm(-3).
