Scientific paper

We report improved measurements of exclusive two-body charmless hadronic B meson decays B -> eta' h, where h is a charged kaon or pion or a K^0. These results are obtained from a data sample that contains 386 million B Bbar pairs collected at the Upsilon(4S) resonance, with the Belle detector at the KEKB asymmetric energy e+ e- collider. We measure BF(B^0 ->eta' K^0) = (56.6 ^{+3.6}_{-3.5} +- 3.3) x 10^-6, BF(B^+ -> eta' K^+) = (68.6 +- 2.1 +- 3.6) x 10^-6 and BF(B^+ -> eta' pi^+) = (1.73 ^{+0.69}_{-0.63} +- 0.12) x 10^-6, where the first and second errors are statistic and systematic, respectively. The CP asymmetries in the charged modes are measured and no evidence for direct CP violation is found. We measure ACP(B -> eta' K^+) = 0.03 +- 0.03 +- 0.02 and ACP(B -> eta' pi^+) = 0.15 ^{+0.39}_{-0.38} ^{+0.02}_{-0.06}.
