Description
Summary:Results of a partial-wave analysis for the reaction {pi}{sup -} {sup {yields}} {omega}{omega}n studied at the VES spectrometer (Institute for High Energy Physics, Protvino) are presented. The behavior of the J{sup PC} = 2{sup ++} amplitudes in the {omega}{omega} system is described by the f{sub 2}(1565) and f{sub 2}(1910) resonances, whose parameters were fixed at M = 1.590 {+-} 0.010 GeV and {gamma} = 0.140 {+-} 0.011 GeV for the former and at M = 1.890 {+-} 0.010 GeV and {gamma} = 0.165 {+-} 0.019 GeV for the latter. The decay f{sub 4}(2050) {sup {yields}} {omega}{omega} was observed at parameters values of M = 1.960 {+-} 0.015 GeV, {gamma} = 0.290 {+-} 0.020 GeV.
