An unknown material was ground to a fine powder and subjected to x-ay diffraction measurement using a Bruker V8 system with Cukα radiation with wavelength λ= 1.452 Å. The following 2θ values were recorded: 28.5o, 47.4o, 56.1o, 28.5o, 69.1o, and 76.2o. Calculate the d spacing associated with each peak and Identify the miller indices for each XRD peak. Calculate the lattice parameter of this material assuming that it has a cubic structure then state what is this material.
