A momentum-analyzed, isomeric, radioactive {sup 18}F{sup {ital m}} beam ({ital E}{sub {ital x}}=1.12 MeV, {ital T}{sub 1/2}=163 ns) has been produced with the reaction {sup 12}C({sup 17}O,{sup 18}F{sup {ital m}}){sup 11}B at {ital E}({sup 17}O)=70 MeV. The {sup 18}F{sup {ital m}} ions were focused onto a secondary target using a compact superconducting solenoid lens and scattering of {sup 18}F{sup {ital m}} from Au and carbon targets was observed. A conversion efficiency of {gt}10{sup 3} {sup 18}F{sup {ital m}}/s per 100 particle nanoamps of {sup 17}O was obtained using a 1.1 mg/cm{sup 2} natural carbon production target.
