Abstract
We describe searches for decays to two-body charmless final states eta(')eta, eta(')pi(0) and eta pi(0) of B-0 mesons produced in e(+)e(-) annihilation. The data, collected with the BABAR detector at the Stanford Linear Accelerator Center, represent 232x10(6) produced B (B) over bar pairs. The results for branching fractions are, in units of 10(-6) (upper limits at 90\% C.L.): B(B-0->eta(')eta)=0.2(-0.5)(+0.7)+/- 0.4(< 1.7), B(B-0->eta pi(0))=0.6(-0.4)(+0.5)+/- 0.1(< 1.3), and B(B-0->eta(')pi(0))=0.8(-0.6)(+0.8)+/- 0.1(< 2.1). The first error quoted is statistical and the second systematic.
