We present a measurement of the mass difference Amd of the two °mass eigenstates. We use a flavor tagging method based on the lepton charge, in a sample of events with two muons at low transverse momentum. The sample corresponds to an integrated luminosity of 90 pb' collected by the Collider Detector at Fermilab. The result obtained is Amrf=0.503±0.064(stat)±0.071(syst) ps~'.
