Many final states such as $ηπ$, $η' π^{-}$, $a_{0} π$, $f_{1} π$, $a_{2} π$, $b_{1} π$, which are favored decay modes of exotics, are under investigation.9 pages, PostScript, Presented at the International School of Nuclear Physics, Erice, Sicily, Italy, September 1995High Energy Physics - Experimenttext
