It is shown that the spin asymmetry in the reaction {pi}{sup -}p {yields} a{sup 0}{sub 0}(980)n {yields} ({eta}{pi}{sup 0}){sub S} n is highly sensitive to the mixing of the a{sup 0}{sub 0}(980) and f{sub 0}(980) resonances. At low momentum transfers (namely, in any of the intervals 0 {<=} -t {&l...
