2. From electron scattering experiments using 420 MeV electrons, a minimum in the scattering is observed at 51° with respect to the direction of the beam for 12C targets (see plot below). The shape of the scattered intensity as a function of scattering angle resembles that seen for the diffraction patterm of a disc or a circular aperture. Use this information to estimate the radius of the 12C nucleus. How does your estimate compare with that of a more rigourous treatment of the scattering problem (slide 21 of Part 1 notes)? 10-1 10-2 Scattered intensity (arbitrary units) 160, 360 MeV 160, 420 MeV 10-3 12C, 420 MeV 10-4 10-5 30 40 40 50 Scattering angle (degrees) 60 60 70 70
