Using a representation of the quark distribution inside the proton, where a short-range correlation between quarks is considered, we can describe the p-p elastic scattering differential cross section with experimental agreement in the range 0 :::; q2 :::; 10 (GeV/ c)2. Evaluations of the proton core and quark radii are obtained. From our analysis, we see that the suggested configuration of quarks inside the proton can be considered as a nearly realistic distribution even with a non-relativistic wavefunction.
