Abstract
A partial wave analysis of the reaction ($) over bar pp-->pi(0) eta et a has been performed, using a high quality, high statistics data set o f 198,000 events. In addition to the f(0)(1370), a second scalar reson ance decaying into eta eta, the f(0)(1500), with mass m =(1505 +/- 15) MeV and width Gamma = (120 +/- 30) MeV has to be introduced to descri be the data.
