Question 2 Electrons are used as the probing particle in modern nuclear scattering experiments of elements. The following graph shows how the variation in intensity of electrons detected varies with scattering angle for such an experiment. 1 Relative intensity of scattered electrons 104 102 100 104 10 36 + Scattering angle, 8 / degrees a) If the wavelength of the incident electrons is 4.0fm, calculate the radius of the atomic nucleus that has scattered them. b) Explain the advantage of using electrons rather than alpha particles as the scattering particles for investigating the size of atomic nuclei.
