We report on new measurements for the mass, width and branching ratios for the J/ ψ, ψ′, X c1 and X c2 .These charmonium states are formed in exclusive proton-antiproton annihilations at the Fermilab Antiproton Accumulator ring, where stochastically cooled antiprotons are brought into collision with the protons of an internal hydrogen gas jet target. The antiproton energy was precisely controlled and measured allowing for an accurate measurement of the resonance parameters.
