指出通过测量X（3872）→ D_0 D_0π_0和X（3872）→ D_0 D_0 π_0γ衰变的速率和能谱，可以较详细地研究D_0 D_0 π_0阈值下窄共振X（3872）的内部结构。特别是，如果这个共振包含一个占主导地位的“分子”成分D D ± D D，这个成分可以通过D 0和D 0的基本衰变之间的一种独特的干涉模式来揭示和研究，其相干性由X（3872）的固定（但未知）C宇称来保证。
It is pointed out that the internal structure of the narrow resonance X(3872) at the D0D ̄∗0threshold can be studied in some detail by measuring the rate and the spectra in the decays X(3872)→D0D ̄0π0and X(3872)→D0D ̄0γ . In particular, if this resonance contains a dominant “molecular” component D D∗̄ ± D ̄ D∗, this component can be revealed and studied by a distinct pattern of interference between the underlying decays of D∗0and D ̄∗0whose coherence is ensured by fixed (but yet unknown) C parity of the X(3872).
