The deuteron, with the size being 1. 96fm and the binding energy being 2. 25MeV, is a highly extended object. In order to reproduce the deuteron properties well, a long-range tail should be introduced phenomenologically.

氟核的方均根半经~1.96fm、束缚能B=2.25MeV，是个结合得很松散的束缚态，要定量的解释氘核必须唯象引进核力中的长程部分，而长程部分主要由π交换提供。
