Steve, You can see from the Wiki entry that q(1) and q(2) are related to charge via the number of protons, and would make a strong difference - essentially making it more difficult to overcome this barrier without high velocity (or high heat being the same thing) .... as it is the brute force of kinetic energy which drives the repelling particles close enough for the strong interaction to take place in "hot" fusion regimes.
As mentioned in the Wiki entry, temperatures needed to overcome the Coulomb barrier in practice turn out to be smaller than expected due to QM tunneling, as established by Gamow. In the Farnsworth Fusor we can see the vivid evidence of this, since tunneling lowers that barrier threshold - which is listed in many physics textbooks as over a million volts, all the way down to about 20 kilovolts. Tunneling is a resonance phenomenon and can be enhanced even further with a preferred resonance and strong coupling. "The consideration of barrier-penetration through tunneling and the speed distribution gives rise to a limited range of conditions where the fusion can take place, known as the Gamow window." To that enhance the Gamow window with strong coupling - you could add the influence of opposite charge in confined space and keep the resonance at a semi-coherent level. On the Wiki page: http://en.wikipedia.org/wiki/Proton-proton_chain Notice that the P-e-P reaction is mentioned in the solar context -- and further imagine that the D-e-D or P-e-D variants of that in a metal matrix-- which could be potential variations which might be seen in some versions of LENR (those with little helium). With strong coupling, these reactions might be highly favored over the low rates seen in a solar environment. Also note - in regard to the lack of radiation in LENR experiment - that the neutrino can carry away energy in those reactions with no obvious effects - which would then make the energy deposited by the ash much less. You could even see transmutation and endotherm together. BTW - some of Mills' hydrino heat could relate to P-e-P ... in which case deuterium is in there as a reactant whether he likes it or not. Jones My apologies if this question has already been answered: Does the radius of the Coulomb barrier change with the size and number of protons and neutrons associated with a nucleus? I wuz wondering if the CB was a fixed constant. Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks
