*It isn't clear to me why a cooper pair of protons would be of nuclear dimensions, nor why they would be able to surmount the Coulomb barrier.*
Essentially, there exists no Coulomb barrier at the point of charge concentration if that concentration is dense enough. These days, I am interested in concentration of electron charge in a small volume. This is how the Chin reaction works. Rossi’s reaction is inferior in my opinion as hard to control. In the Chin reaction, this negative electric charge concentration on a nano tube will induce a large number of positive charge holes of equal by opposite charge. Now See http://en.wikipedia.org/wiki/Electric-field_screening *Electric-field screening* The main point here is that as long as there are many positive ions between two positive charges; say a proton and a nucleus, their interaction is * screened* strongly, simply because these many positive charge carriers can terminate electric field lines. So a free ion attracts ions of opposite sign, making a little `counter ion cloud' which neutralizes its charge, and therefore by Gauss's law, basically eliminates the electric field. The size of this `cloud' is roughly the screening length yD, the parameter that determines when the exponential `cuts off' the Coulomb interaction in U(r). A useful formula for yD is due to Debye, which comes from a certain relatively-easy-to-solve limiting case of interaction of charges with free ions present where the sum over j is over *all* the ions, and where j counts the number of ions. As you can see, as you add more and more positve charges, because the induced charges enter squared, the screening length goes down, down, down. See the function for the Debye-Hückel length where Zj = Qj/C is the integer charge number<http://en.wikipedia.org/wiki/Charge_number>that relates the charge on the j-th ionic species to the elementary charge<http://en.wikipedia.org/wiki/Elementary_charge> . http://en.wikipedia.org/wiki/Debye_length *Debye length******* ** This formula is often called the *Debye screening length*, and provides a good first estimate of the distance beyond which Coulomb interactions can be essentially ignored, as well as the size of the region near a point charge where opposite-charge counter ions can be found.
