Question

A beam of electrons with energies of 250 MeV is scattered through an angle of 100 by a heavy nucleus. It is found that the differential cross-section is 65% of that expected from scattering from a point nucleus. Estimate the root mean square radius of the nucleus

Answer 1

Answer: The radii of atomic nuclei are of the order of 50×10^-15 to the negative 15th power.
