Abstract
Data samples corresponding to the isospin-violating decay D-s(*+)-> D(s)(+)pi(0) and the decays D-s(*+)-> D(s)(+)gamma, D-*0-> D(0)pi(0) and D-*0-> D(0)gamma are reconstructed using 90.4 fb(-1) of data recorded by the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) collider. The following branching ratios are extracted: Gamma(D-s(*+)-> D(s)(+)pi(0))/Gamma(D-s(*+)-> D(s)(+)gamma)=0.062 +/- 0.005(stat.)+/- 0.006(syst.) and Gamma(D-*0-> D(0)pi(0))/Gamma(D-*0-> D(0)gamma)=1.74 +/- 0.02(stat.)+/- 0.13(syst.). Both measurements represent significant improvements over present world averages.
