Give 2 reasons which give support for the quark substructure of protons and neutrons
The Attempt at a Solution
My first reason was due to the fact that in deep elastic scattering of the electron from a proton, the analysis of the structure function (fourier transform) showed the charge distribution of the proton was not a dirac delta functon, and hence the proton has structure, further analysis found quarks were in fact point like and therefore fundamental.
I cannot think of another reason which is valid. I thought maybe something about how when you collide things at high energies quark antiquark pairs are created? but I don't think that right.
Any help would be fab thank you!
