We have predicted that B(D^*+→D⁺γ) is between 0.4% and 2% using data from the similar decays of D^*0 and D^*0 mesons. Our calculation is based on an effective field theory with expansions in external momentum and heavy-quark mass. We also have calculated the K^* branching fractions and found reasonable agreement between theory and experiment. Our calculation suggests that nonleading terms in the quark-mass expansion may still be quite important for both s and c quarks.
