The branching ratio for the decay mode D[sup +] [yields] [bar K]*[sup 0] [mu][sup +][nu] has been measured with two methods. The first uses D[sup 0] [yields] [bar K] [sup [minus]][mu][sup +][nu] for normalization, and yields the result B(D[sup +] [yields] [bar K]*[sup 0] [mu][sup +][nu] = (3.25 [plus minus] 0.71 [plus minus] 0.75)%. From this method we also obtain the direct measurement [Gamma](D[sup +] [yields][bar K]*[sup 0][mu][sup +] [nu]/[Gamma](D[sup 0] [yields] K[sup [minus]] [mu][sup +] [nu]) = 0.43 [plus minus] 0.09 [plus minus] 0.09. The second method uses the mode D[sup +] [yields] K[sup [minus]][pi][sup +] [pi][sup +] for normalization and yields B(D[sup +] [yields] [bar K]*[sup 0] [mu][sup +][nu]) = 4.18 [plus minus] 0.66 [plus minus]0.96)%. Combining the results of the two methods yields B(D[sup +] [yields] [bar K]*[sup 0][mu][sup +][nu]) = 3.57 [plus minus] 0.96)%.
