Abstract

An enhancement in the

2 π^{0}

mass spectrum in the region

M_{π π} < 1

GeV has been observed in

π^{-} + p \to π^{0} + π^{0} + n

at 10

\frac{GeV}{c}

. This is interpreted as a broad isospin-0,

s

-wave resonance at 600±100 MeV with width 400±100 MeV. Because of limited mass resolution, we cannot rule out several narrower resonances with these quantum numbers.
