We report on a measurement of inverse muon decay νμ+e→μ-+νe at the Fermilab Tevatron. A sample of 1151 inverse-μ-decay events, produced by neutrinos with laboratory energy in the range 15≤Eν≤600 GeV, is extracted. We measure the rate of this reaction with respect to the νμ-N charged-current interaction to be [0.125±0.009(stat)±0.003(syst)]×10-2. The measurement supports V—A structure of the weak current, left-handed two-component neutrinos, and a cross section rising linearly with respect to the center-of-mass energy.
