Description
The reaction π-p→ηπ0n has been studied with GAMS-2000 spectrometer in the secondary 38 GeV/c π--beam of the IHEP U-70 accelerator. Partial wave analysis of the reaction has been performed in the ηπ0 mass range up to 1200 MeV. The a0(980)-meson is seen as a sharp peak in S-wave. The t-dependence of a0(980) production cross section has been studied. Dominant production of the a0(980) at a small transfer momentum t confirms the hypothesis of Achasov and Shestakov about significant contribution of the ρ2 exchange (IGJPC=1+2--) in the mechanism of a0(980) meson production in t-channel of the reaction
