Abstract: (arXiv)

We perform the first three-dimensional measurement of the amplitudes of

B\to \psi(2S) K^*

and

B\to \chi_{c1} K^*

decays and update our previous measurement for

B\to J/\psi K^*

. We use a data sample collected with the BaBar detector at the PEP2 storage ring, corresponding to 232 million

B\bar B

pairs. The longitudinal polarization of decays involving a

J^{PC}=1^{++}

\chi_{c1}

meson is found to be larger than that with a

1^{--}

J/\psi

or

\psi(2S)

meson. No direct {\it CP}-violating charge asymmetry is observed.
