N2 - A precision measurement of the mass difference between the D0 and D∗0 mesons has been made using 316pb-1 of e+e- annihilation data taken at s=4170MeV using the CLEO-c detector. We obtain ΔM≡M(D∗0)-M(D0)=142.007±0.015(stat)±0.014(syst)MeV, as the average for the two decays, D0→K-π+ and D0→K-π+π-π+. The new measurement of ΔM leads to M(D∗0)=2006.850±0.049MeV, and the currently most precise measurement of the binding energy of the "exotic" meson X(3872) if interpreted as a D0D∗0 hadronic molecule, Eb(X(3872))≡M(D0D∗0)-M(X(3872))=3±192keV.
