Two reacting nuclei, maximum distance to overcome the coulomb barrier

[eddiej90]

Basically I'm trying to find out how to find the maximum distance between two deuterium nuclei in order to overcome the coulomb barrier, causing them to fuse.

Thanks

Roughly, the range of the strong nuclear force is 1 fm. There is no sharply defined distance that can be defined in answer to your question.
