Resonant formation of d{mu}t molecules in collisions of muonic tritium ({mu}t ) on D{sub 2} was investigated using a beam of {mu}t atoms, demonstrating a new direct approach in muon catalyzed fusion studies. Strong epithermal resonances in d{mu}t formation were directly revealed for the first time. >From the time-of-flight analysis of 2036{+-}116 dt fusion events, a formation rate consistent with 0.73{+-}(0.16){sub meas}{+-} (0.09){sub model} times the theoretical prediction was obtained. For the largest peak at a resonance energy of 0.423{+-}0.037 eV , this corresponds to a rate of (7.1{+-}1.8)x10{sup 9} s{sup -1} , more than an order of magnitude larger than those at low energies.
