    Basically, I've worked out the binding energy for deuterium-tritium fusion and for deuterium-helium-3 fusion, and I'd like to compare the coulomb barriers. I know the equation is U=(kQq)/r or U=(kZze^2)/r as its just electrical potential, however both fusion reactions would therefore have the same coulomb barrier because of the same amount of protons and thus charge?? I thought deuterium-helium-3 had a higher coulomb barrier? How do I show this?
