A search was made for a T = 0 3 pi resonance in the mass region m/sub i3m, where the decay omega yields pi /sup +/ + pi /sup -/ + pi /sup 0/ is pos sible. The reaction p-bar.+ p yields pi /sup +/ + pi /sup +/ + pi / sup -/ + pi /sup 0/ was studied by measuring 2500 four-prong events produced by antiprotons of 1.61 Bev/c in the 72-in. bubble chamber. Tabular and graphical data are presented that fit the qualitative criteria for an axial vector matrix element ( omega meson). There is reasonable evidence against both the A and PS mesons. (L.N.N.)
