The authors have searched for the decays B{sup 0} {yields} D{sub s}{sup +}a{sub 0}{sup -}, B{sup 0} {yields} D*{sub s}{sup +} a{sub 0}{sup -}, B{sup 0} {yields} D{sub s}{sup +}a{sub 2}{sup -} and B{sup 0} {yields} D*{sub s}{sup +} a{sub 2}{sup -} in a sample of about 230 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. They find no evidence for these decays and set upper limits at 90% C.L. on the branching fractions: {Beta}(B{sup 0} {yields} D{sub s}{sup +} a{sub 0}{sup -})
