摘要：

A partial-wave analysis of the reaction p $($) over bar$$ p-->pi(0) pi(0) pi(0) has been performed using a high-quality high-statistics data set of 712 000 events. In addition to the f(0)(975) and f(0)(1300), the scalar resonance with mass m = (1500 +/- 15) MeV and width Gamma = (120 +/- 25) MeV is necessary to describe the data.
