  "abstract": "Over the last twenty years, it was assumed that the reaction $\\pi^-p\\to a^0_0(980)n\\to\\pi^0\\eta n$ at high energies is dominated by $b_1$ Regge pole exchange. We show that the new Brookhaven and Serpukhov data on the $t$ distributions for this reaction can be explained within the framework of the Regge pole model only if the $\\rho_2$ Regge pole exchange conspiring with its daughter plays a crucial role. The tentative estimates of the absolute $\\pi^-p\\to a^0_0(980)n\\to\\pi^0\\eta n$ reaction cross section are obtained. The contributions of the one-pion exchange mechanism and the Regge cuts are also estimated.",
