Two-gluon coupling of gluonic mesons is estimated in a spectator model to be considerably larger than that of .As an example of a gluonic meson that may be produced in radiative decay, we analyse . We deduce from experimental data that its branching ratio to two gluons is bounded, ,consistent with a gluonic meson, but not compelling it. We propose further tests, and estimate the two-photon coupling of to be keV.
