What is Bragg Scattering angle ? (first order)for an electrons beam scattered / diffracted from the surface of Ni crystal with atomic- planes spacing D= 0.215 nm and the kinetic energy of the electron beam is 75 eV. What happens to Scattering angle if the energy of the electron beam is increased to 100 eV?
