The decays B{sup +} {r_arrow} D{sup *+}{sub s}{gamma} and B{sup +} {r_arrow} D{sup *+}{gamma} can be used for an extraction of {vert_bar}V{sub ub}{vert_bar}. When the b and c quarks are nearly degenerate the rate for these modes can be determined in terms of other observed rates, namely B{anti B} mixing and D{sup *} {r_arrow} D{gamma} decay. To this end the authors introduce a novel application of heavy quark and flavor symmetries. Although somewhat unrealistic, this limit provides them with a first estimate of these rates.
