Abstract

We report results from a high-statistics study of the reaction

π^{-} p \to n π^{0} π^{0}

between 1.6 and 2.4 GeV/c, in which all the final-state particles were detected. The

2 π^{0}

mass spectrum exhibits a marked enhancement in the region of 800 MeV, which is narrower in width than predicted by the recently reported "down-down" solution for

I = 0

S

-wave,

π - π

phase shifts.
