Study of B Decays to Charmonium States $B\to {\eta }_{c}K$ and $B\to {\chi }_{C0}K$

K. W. Edwards, CLEO Collaboration

In a sample of $9.66\times 10^{6}B\bar{B}$ pairs collected with the CLEO detector we make the first observation of B decays to an ${\eta }_c$ and a kaon. We measure branching fractions $B…
