The first results from an experiment to deflect a beam of fully stripped, ultrarelativistic Pb{sup 82+} ions of 400 GeV/c per unit of charge, equivalent to 33 TeV/c , by means of a bent crystal are reported. Deflection efficiencies are as high as 14{percent}, in agreement with theoretical estimates. In a second experiment a bent crystal was used to extract 270 GeV/c -per-charge Pb{sup 82+} (22 TeV/c) ions from a coasting beam in the CERN-SPS, and a high extraction efficiency of up to 10{percent} was found. These represent the first measurements to demonstrate applications of bent crystals in high energy heavy ion beams. {copyright} {ital 1997} {ital The American Physical Society}
