In a Davisson-Germer-like diffraction experiment, electrons of kinetic energy 80 eV are in normal incidence on the surface of a single crystal of an unknown solid. Suppose the first-order peak in the diffraction intensity (see figure in class notes) occurs at an angle of 29° with respect to the surface normal. Find the distance between rows of atoms on the surface of the crystal.
