Quark Bonding Lengths
internal and external to nucleons
|
Quarks in this model are understood to be fundamental particles just as electrons are fundamental particles. The proton is composed of two up quarks and one down quark  Three quarks form triangular shaped nucleon particles. The color force (gluons) is the strongest force in the nucleus; however, the electrical and magnetic forces also have some attractive and repulsive effects. |

The force between the up and down quarks is attractive and always the same, however the electric forces between two up quarks in the proton and two down quarks in the neutron are repulsive thus the triangular form of nucleons deviate slightly from an equilateral triangle. The repulsion of the two up quarks in the proton is greater than the repulsion of the two down quarks in the neutron. The two down quarks are slightly closer than the two up quarks, thus protons and neutrons each have a slightly different shape and size. The proton should be slightly larger than the neutron. So now the short answer is; no they are not all the same length, however they are very close to the same length. The approximate length of the average bond by our preliminary calculations is on the order of about 0.8 fm. + 0.1 fm. |
