Using B to charmonium decays we find that the neutral B fraction in Y(4S) decays is nearly half, that the CP asymmetries in J/ψK^(-/+) and psi' K^(-/+) are small, and we also report on the first observation of B->eta_c K.Presented at XXXth International Conference on High Energy Physics July 27 - August 2, 2000, Osaka, Japan; 3 pages & 3 figuresHigh Energy Physics - ExperimentHigh Energy Physics - Phenomenologytext
