Question 2 Relative intensity of scattered alartrans 1 101 102 103 104 105 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. Scattering angle, 0 / degrees 30 40 50 60 70 a) If the wavelength of the incident electrons is 4.0 fm, 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.
