Measurement of the decay fractions of D* mesons

Using the ARGUS detector at the DORIS II electron-positron storage ring at DESY, we have measured BR(D*+→D0π+)=(68.8±2.4±1.3)%, BR(D*+→D+π0)=(31.2±1.1±0.8)%, BR(D*+→D+γ)<5.2% (90%CL), BR(D*0→D0π0)=(59.6±3.5±2.8)%, and BR(D*0→D0γ)=(40.4±3.5±2.8)%, and the mass difference Δm0=m(D*0)−m(D0)=(142.2±0.3±0.2)MeV/c2.
