The enhancement of dielectronic recombination by applied electric fields has been observed and measured for the first time in a wide range of controlled and measurable fields using multiply charged ions. The heavy ion storage ring CRYRING at Stockholm University was used to store a beam of Si{sup 11+} and collide it with a cold electron target. Rydberg resonances up to n=25 are resolved for both the 2p{sub 3/2} and 2p{sub 1/2} series. The observation of a substantial monotonic increase of the rate coefficient for the group of higher Rydberg states is in puzzling disagreement with theoretical calculations of electric field enhanced dielectronic recombination. {copyright} {ital 1997} {ital The American Physical Society}
