The decays B0D*+D*-, B0D*±D and B0D+D- are studied in 9.7×106Υ(4S)→BB̅ decays accumulated with the CLEO detector. We determine B(B0D*+D*-)=(9.9-3.3+4.2[stat]±1.2[syst])×10-4 and limit B(B0D*±D)<6.3×10-4 and B(B0D+D-)<9.4×10-4 at 90% confidence level (C.L.). We also perform the first angular analysis of the B0D*+D*- decay and determine that the CP-even fraction of the final state is greater than 0.11 at 90% C.L. Future measurements of the time dependence of these decays may be useful for the investigation of CP violation in neutral B meson decays.
