Description:	We report the observation of a narrow state decaying into J/ψπ+π- and produced in 220 pb-1 of p̄p collisions at √s=1.96 TeV in the CDF II experiment. We observe 730±90 decays. The mass is measured to be 3871.3±0.7(stat)±0.4(syst) MeV/c2, with an observed width consistent with the detector resolution. This is in agreement with the recent observation by the Belle Collaboration of the X(3872) meson.
