Abstract

We report measurements of the radiative decay [Formula Presented] The analysis is based on a data sample containing [Formula Presented] B meson pairs collected by the Belle detector at the KEKB storage ring. We measure branching fractions of [Formula Presented] and [Formula Presented] where the first and second errors are statistical and systematic, respectively. The isospin asymmetry between [Formula Presented] and [Formula Presented] decay widths is measured to be [Formula Presented] assuming an equal production rate for [Formula Presented] and [Formula Presented] pairs from the [Formula Presented] resonance. We search for a partial rate asymmetry between [Formula Presented] conjugate modes, and find [Formula Presented]
