Abstract

We report branching fraction measurements for exclusive decays of charged and neutral B mesons into two-body final states containing a charmonium meson. We use a sample of

22.72 \pm 0.36

million

B \bar{B}

events collected between October 1999 and October 2000 with the BABAR detector at the PEP-II storage rings at the Stanford Linear Accelerator Center. The charmonium mesons considered here are

J / ψ,

ψ (2 S),

and

χ_{c 1},

and the light meson in the decay is either a K,

K^{*},

π^{0} .
