| Abstract: | We have calculated the mean square charge radii of the neutron and proton, and compared them with the experimental values,
to construct a unique non-relativistic quark potential model. It is shown for the first time that, contrary to general belief,
it is possible to reproduce simultaneously the baryon mass spectrum and the electromagnetic sizes of neutron and proton using
a single potential model. It was found necessary to add admixtures of excited states of the nucleon in the unperturbed ground
state wavefunctions. |
