Abstract
We have observed a signal for the decay D(+) --> D(+)gamma at a signi ficance of 4 standard deviations. From the measured branching ratio B( D(+) --> D(+)gamma)/B(D*(+) --> D(+)pi(0)) = 0.055 +/- 0.014 +/- 0.01 0 we find B(D(+) --> D(+)gamma) = 0.017 +/- 0.004 +/- 0.003, where th e first uncertainty is statistical and the second is systematic. We al so report the highest precision determination of the remaining D(+) b ranching fractions.
