comment Why are the dineutron and diproton unbound?
@BenCrowell sure I agree, this is why I didn't roll back your edits, since they are ok. If there is no general question about nonexistence of nn and pp on SE yet, then it should be here of course.

comment Why are the dineutron and diproton unbound?
My question was quantitative, and now you made it qualitative. I would like a plot U(r) for neutrons and protons.

comment What is $\delta$ in this formula?
What is "expanded string"? If I am right, then the definition of $\delta$ should present somewhere else in textbook. Also it can be unknown or known only by some properties. May be it is possible to suggest that orientation distribution is isotropic.
