Fermilab experiment E-760 studies the resonant formation of charmonium states in proton-antiproton interactions using a hydrogen gas-jet target in the Antiproton Accumulator ring at Fermilab. Precision measurements of the mass and width of the charmonium states chi-c1,chi-c2, a direct measurement of the psi' width, and a new precision measurement of the J/psi mass are presented.

Abstract
Fermilab experiment E-760 studies the resonant formation of charmonium states in proton-antiproton interactions using a hydrogen gas-jet target in the Antiproton Accumulator ring at Fermilab. Precision measurements of the mass and width of the charmonium states chi-c1,chi-c2, a direct measurement of the psi' width, and a new precision measurement of the J/psi mass are presented.
