Abstract

The number of pseudoscalar mesons in the mass range from 1400 to 1500 MeV/c² 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 π^- p → K⁺K^-π⁰n has been made at a beam energy of 18 GeV. A partial wave analysis of the K⁺K^-π⁰ system shows evidence for three pseudoscalar resonances, η(1295), η(1416), and η(1485), as well as two axial vectors, f₁(1285), and f₁(1420). Their observed masses, widths and decay properties are reported. No signal was observed for C(1480), an I^GJ^PC = 1⁺1^-- state previously reported in øπ⁰ decay.
