An X-ray diffraction (XRD) experiment is carried out on a crystalline solid having FCC structure at room temperature. The solid undergoes a phase transformation on cooling to
—20 °C and shows orthorhombic structure with small decrease in its unit cell lengths as compared to the FCC unit cell lengths. As a result, the (311) line of the XRD pattern corresponding to the FCC system
(A) will split into a doublet.
(B) will split into a triplet.
(C) will remain unchanged.
D) will split into two separate doublets.

(a) A solid having a simple cubic structure at room temperature with lattice parameter a and one valence electron per atom, is assumed to show free electron behaviour. Calculate the ma2nitude of the Fermi wave vector and the corresponding equivalent
temperature. (12)
(b) Find the ratio of the magnitude of the Fermi wave vector to the radius of the largest sphere that can be inscribed within the first Brillouin zone of the solid. (9)
