摘要

Physics and Astronomy (all)
We report observations of radiative [Formula presented] meson decays into the [Formula presented] and [Formula presented] final states. In the [Formula presented] channel, we present evidence for decays via an intermediate tensor meson state with a branching fraction of [Formula presented]. We measure the branching fraction [Formula presented], in which the [Formula presented] and [Formula presented] channels dominate. The analysis is based on a data set of [Formula presented] recorded by the Belle experiment at the KEKB collider. © 2002 The American Physical Society.
