A photon of wavelength 157nm strikes an aluminium surface along a line perpendicular to the surface and releases a photoelectron travelling in the opposite direction. Assume the recoil momentum is taken up by a single aluminium atom on the surface. Calculate the recoil kinetic energy of the atom. Would this recoil energy significantly affect the kinetic energy of the photoelectron? (The atomic mass of aluminium is 26.98u).
