Electrons accelerated to an energy of 49 GeV have a de Broglie wavelengthλ small enoughfor them to probe the structure within a target nucleus byscattering from the structure. Assume that the energy is so largethat the extreme relativistic relation p = E/cbetween momentum magnitude p and energy Eapplies. (In this extreme situation, the kinetic energy of anelectron is much greater than its rest energy.)
(a) What is λ?
1fm
(b) If the target nucleus has radius R = 4.8 fm, what is the ratioR/λ?
