A lattice is defined by the following basis vectors in units of nanometres. a/2 a/3 a/2 412 a1 = (0.50, 0.0, 0.0), a2 = (0.0, 0.40, 0.30), a3 = (0.30, 0.0, 0.50) (a) Calculate the associated reciprocal lattice vectors and their lengths. (b) A material with the lattice from part (a) and a single atom basis is characterised by a powder diffraction experiment. If the x-rays have a wavelength of 0.1 nm find the three lowest Bragg angles for diffraction rings observed in the experiment. Hint: You will only need to consider Miller indices up to a maximum | h |, | k | and | L | of 1.
