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 Xc0 mass and width, preliminary results of analysis of the Xc0 decay to π0π0 and γγ and the final value of our measurement of the ηc parameters.
