  New experimental information on the non-exotic J^PC = 0^-+ isovector seen at
1.8 GeV by VES yields convincing evidence of its excited gluonic (hybrid)
nature when a critical study of alternative quarkonium assignments is made in
the context of ^3 P_0 decay by flux-tube breaking. Production of this gluonic
excitation via meson exchange is promising, although its two photon production
vanishes.
