Bragg diffractionX-rays are scattered in a Bragg diffraction experiment from the (111) planes of aluminum using a wavelength corresponding to 8 keV. The crystal structure of aluminum is fcc and the lattice constant (length of the conventional unit cell) is 4.04 Å. Calculate the scattering angle 2θ (the angle enclosed by the primary beam and the scattered beam) for the primary reflection, n = 1. |
