Abstract Using the ARGUS detector at thee + e − storage ring DORIS II, we have measuredB decays into exclusive final states containing aD orD * meson plus several pions, or containing aJ/ψ or ψ′ meson plus a strange particle. Some of these channels have not been seen before, while others represent updated measurements of previous results. The branching ratios are compared with the predictions of the model of Bauer, Stech and Wirbel. Using the cleanest decay channels, the mass of the charged and neutralB meson are found to bem B −=(5280.5±1.0±2.0) MeV/c2 andm B 0=(5279.6±0.7±2.0) MeV/c2 respectively, yielding a mass differencem B 0−m B − =(−0.9±1.2±0.5) MeV/c2.
