Over the last twenty years, it was assumed that the reaction {pi}{sup -}p{yields}a{sub 0}{sup 0}(980)n{yields}{pi}{sup 0}{eta}n at high energies is dominated by the b{sub 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}{sub 2} Regge pole exchange conspiring with its daughter plays a crucial role. The tentative estimates of the absolute {pi}{sup -}p{yields}a{sub 0}{sup 0}(980)n{yields}{pi}{sup 0}{eta}n reaction cross section are obtained. The contributions of the one-pion exchange mechanism and the Regge cuts are also estimated.
