The and decays (with the charge conjugated ones) are the direct probe of the constituent two-quark components in the and wave functions. Recent BESIII experiment is the first step in experimental study of these decays. We suggest adequate formulas for the data analysis and present a variant of ηπ invariant mass distribution when a0(980) has no constituent two-quark component at all.
