Popis: We present here the results of the VES experiment obtained in 1992–1993: 1) The partial-wave analysis (PWA) has been performed for the reactions\(\pi ^ - \mathcal{N} \to \eta \pi ^ - \mathcal{N}\) and\(\pi ^ - \mathcal{N} \to \eta \pi ^ - \mathcal{N}\). It has been shown that the intensity of the exotic wave withJPC=1−+ for the η′π- system significantly exceeds that for the ηπ- system. 2) The PWA has been performed for the reactions\(\pi ^ - \mathcal{N} \to \pi ^ + \pi ^ - \pi ^ - \mathcal{N}\) and\(\pi ^ - \mathcal{N} \to {\rm K}^ + {\rm K}^ - \pi ^ - \mathcal{N}\). The resonance atm=1.8 GeV withJPC=0−+ is clearly seen in both reactions. 3) The radiative decay f1→π(770)γ has been studied. The measured BR(f1(1285)→p0(770)γ)=(3.0±0.7(stat)±0.6(syst))·10-2.
