Abstract

It is pointed out that the internal structure of the narrow resonance X(3872) at the D0D̄*0 threshold can be studied in some detail by measuring the rate and the spectra in the decays X (3872) → D00π0 and X(3872) → D00γ. In particular, if this resonance contains a dominant "molecular" component DD̄*± D̄D*, this component can be revealed and studied by a distinct pattern of interference between the underlying decays of D*0 and D̄*0 whose coherence is ensured by fixed (but yet unknown) C parity of the X(3872).
