We compute B --> Keta((')) branching ratio using perturbative QCD approach. We show that a triangular relation among amplitudes for B-0 --> K(0)pi(0), B-0 --> K(0)eta, B-0 --> K(0)eta' receives large corrections from SU(3) breaking effects. If experimental value will come closer to the lower limit of the present BELLE data there will be a possibility to understand the large branching ratio of B-0 --> K(0)eta'. Otherwise, we perhaps need to modify our understanding of n' meson, for example, inclusion of a possible admixture of gluonium state. (C) 2002 Published by Elsevier Science B.V.
