The decays D0→dūe+ν→a0-(980)e+ν→π-ηe+ν and D+→dde+ν→a00(980)e+ν→π0ηe+ν (and the charge conjugated ones) are the direct probe of the constituent two-quark components in the a0±(980) and a00(980) wave functions. The recent BESIII experiment is the first step in the 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. © 2018 authors.
