Fermilab experiment E-760 light-quark meson spectroscopy data for proton-antiproton annihilation to 3{pi}{sup 0}, 2{pi}{sup 0}{eta}, {pi}{sup 0}2{eta}, and 3{eta} in-flight have confirmed the 1500 MeV state at rest seen previously at CERN. Structures above this energy are complex, and preliminary results of amplitude analysis, in progress, for extracting spin quantum numbers show the possibility of nearly degenerate states for some of these structures. 9 refs., 6 figs., 3 tabs.
