Abstract: 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 ξ c 0 mass and width, preliminary results of analysis of the ξ c 0 decay to μ 0 μ 0 and γγ and the final value of our measurements of the η c parameters.
