Using data taken with the CLEO II detector at the Cornell Electron Storage Ring, we present the first full angular analysis in the color-suppressed modes B0JK *0and B0JK*+. This leads to a complete determination of the decay amplitudes of these modes including the longitudinal polarization ΓL/Γ= 0.52 ± 0.07 ± 0.04 and the P wave component │P2= 0.16 ± 0.08 ± 0.04. In addition, we update the branching fractions for BJK and BJK*.
