Production of this gluonic excitation via meson exchange is promising, although its two photon production vanishes.2 pages, appeared in the Proceedings of XIV International Conference on Particles and Nuclei (PANIC96, Williamsburg, 22-28 May 1996), LaTeX, sprocl.sty includedHigh Energy Physics - Phenomenologytext
