摘要：

The number of pseudoscalar mesons in the mass range from 1400 to 1500 MeV/c(2) has been a subject of considerable interest for many years, with several experiments having presented evidence for two closely spaced states. A new measurement of the reaction pi (-)p --> K(+)K(-)pi (0)n has been made at a beam energy of 18 GeV. A partial wave analysis of the K(+)K(-)pi (0) system shows evidence for three pseudoscalar resonances, eta (1295), eta (1416), and eta (1485), as well as two axial vectors, f(1)(1285), and f(1)(1420). Their observed masses, widths and decay properties are reported. No signal was observed for C(1480), an I-G J(PC) = 1(+)1(--) state previously reported in phi pi (0) decay.
