SOLVED:Robert Hofstadter won the 1961 Nobel prize in physics for his pioneering work in scattering 20 -GeV electrons from nuclei. (a) What is the γfactor for a 20 -GeV electron, where γ=(1-v^2 / c^2)^-1 / 2 ? What is the momentum of the electron in kg ·m / s ? (b) What is the wavelength of a 20 -GeV electron and how does it compare with the size of a nucleus?
