Abstract
We present here the results of the VES experiment obtained in 1992-199 3: 1) The partial-wave analysis (PWA) has been performed for the react ions pi(-) N --> eta pi(-) N and pi(-) N --> eta pi(-) N. It has been shown that the intensity of the exotic wave with J(PC) = 1(-)+ for the eta(')pi(-) system significantly exceeds that for the eta pi(-) syste m. 2) The PWA has been performed for the reactions pi(-) N --> pi(+) p i(-)pi(-) N and pi(-) N --> K+K- pi(-) N. The resonance at m = 1.8 GeV with J(PC) = 0(-)+ is clearly seen in both reactions. 3) The radiativ e decay f(1) --> pi(770)gamma has been studied. The measured BR(f(1)(1 285) --> rho(0)(770)gamma) = (3.0 +/- 0.7(stat) +/- 0.6(syst)).10(-2).
