Abstract: We present a search for B decays to a charged scalar meson a0+ and a pi0where the a0+ decays to an eta meson and a pi+. The analysis was performed on adata sample consisting of 383x10-6 BBbar pairs collected with the Babardetector at the PEP-II asymmetric-energy B Factory at SLAC. We find nosignificant signal and set an upper limit on the product branching fractionBFB+ -> a0+ pi0 x a0+ -> eta pi+ of 1.4x10-6 at the 90% confidence level.
