How the size of the nucleus is experimentally determined by the relation between the radius and mass number of the nucleus? Show that the density of the nucleus is independent of its mass number.

a) Nucleus size determined by scattering experiments, Density independent of mass number due to constant nucleon density
b) Nucleus size determined by Rutherford's gold foil experiment, Density independent of mass number due to constant proton density
c) Nucleus size determined by alpha particle scattering, Density independent of mass number due to constant neutron density
d) Nucleus size determined by X-ray diffraction, Density independent of mass number due to constant electron density
