dc.descriptionWe present preliminary results of the analyses of B into h pi0 and B into hK0 decays (with h = pi+/-, K+/-) from a sample of approximately 60 million BB pairs collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We find evidence for a signal in B+ into pi+ pi0, and we measure the branching fraction BR (B+ into pi+ pi0) = (4.1_{-1.0}^{+1.1}\pm 0.8) 10^{-6}. We also measure the following branching ratios and charge asymmetries: BR(B+ to K+ pi0) = (11.1_{-1.2}^{+1.3} \pm 1.0) 10^{-6}, BR(B+ to pi+ K0) = (17.5^{+1.8}_{-1.7} \pm 1.3)10^{-6}$, BR(B+ to K+ K0bar) < 1.3 10^{-6} (90%$ CL), acp_{pi+ pi0} = -0.02^{+0.27}_{-0.26} \pm 0.10, acp_{K+ pi0} = 0.00\pm 0.11 \pm 0.02$, acp_{pi+ K0} =-0.17\pm 0.10 \pm 0.02, where the errors are statistical and systematic, respectively.
