Question A5A metal oxide is investigated separately by X-ray and neutron diffraction. At room temperature,the unit cells obtained from the two experiments agree well, but at low temperature, the unit cellfrom the neutron experiment appears to be twice as big as that from the X-ray experiment.Give a likely explanation for these observations. Support your explanation with a sketch showingthe unit cells observed by both methods.

a) Approach to solving the question:Understand the key observations from the information…

Question 5 Figure 1 shows a X-ray diffraction pattern from a powdered aluminium sample. The sample was exposed to X-rays of wavelength 1.542x10-10m from a Cuka X-ray source. Assuming the indexing of the lines shown in the figure is correct and that all lines are a result of first order diffraction, calculate the lattice parameter of the structure in nm. Verify your answer by repeating your measurement with a second line. Note the planar spacing d is related to the lattice parameter a by the equation: a d = √h² + k² + 1² Where h, k and I are the miller indices of the plane.
