Abstract
The f(0)(1500) is observed in its <K(K)over bar> decay mode in an ampl itude analysis of high statistics data in <(p)over bar p> annihilation at rest into pi(0)K(L)K(L). The mass and width is found to be (m,Gamm a) = (1515 +/- 20, 105 +/- 15) MeV. A comparison of the decay rate int o 2 pi(0) shows that this state cannot be dominantly <s(s)over bar>. T he f(2)'(1525) has been observed for the first time in <(p)over bar p> annihilation and its production rate is consistent with the expectati on from the OZI rule.
