[edit] What is being exchanged?

Aren't the "exchange interaction" and "exchange force" in the first paragraph two different things? The first results from the antisymmetry of identical fermions without reference to interactions with other particles. The second results from the exchange of bosons, whether the fermions are identical or not. Maybe the "exchange force" should be discussed elsewhere. —JerryFriedman 19:18, 15 February 2007 (UTC)

I am not an expert on this subject, but I think that the example of a gluon (boson) passing between two quarks is inappropriate for this article. The "exchange" being discussed here is two fermions of the same type trading places with each other. When two atoms are close enough that an electron orbital of one overlaps an electron orbital of the other, the two electrons (of the same spin) can trade places in the overlap and this creates a repulsive force also known as the Pauli force.
