Charmonium states at the Fermilab antiproton accumulator. New results from E835 Original Research Article

Experiment E835 has collected a large sample of charmonium states using a hydrogen jet and the virtually monoenergetic stochastically cooled antiproton beam. We present an improved measurement of the ξc0 mass and width, preliminary results of analysis of the ξc0 decay to μ0μ0 and γγ and the final value of our measurements of the ηc parameters.
