Don't use ai to answer I will report you answer The graph below shows the atomic form factor for aluminium determined from theintensities of the diffraction peaks indicated. The labelling is based on the conventionalunit cell, and the curve shown is a theoretical Hartree-Fock calculation.12Hartree-Fock calculation10(111)A = 0.709 A(200)(220)(311)(222)(400)(331)(420)(511)110.10.20.30.40.50.60.70.8sin 6/Aa) Given that the wavelength of the x-rays used is λ = 0.709 angstroms, estimate thelength of the side of the aluminium conventional unit cell.b) Given that the atomic mass of aluminium is 26.98 a.m.u, determine the density ofaluminium.

State whether the following statement is ‘True’ or ‘False’. (2 × 10 = 20) Give a brief explanation for each of your answers, as applicable. Alpha-Polonium has a body-centered cubic structure. True False A dislocation loop must always be a mixed dislocation. True False Divacancies in any metal are present at much higher concentration than monovacancies. True False Generally, a quenched metal has a higher electrical resistivity than an annealed metal. True False Shockley partials are considered glissile in nature. True False Wider stacking faults make cross-slip more difficult, that is why cross-slip in brass (Cu-Zn) is more difficult than copper (Cu). True False According to Hume-Rothery’s rule, the solvent and solute in a substitutional solid solution must have 5% size difference. Pearson symbol of copper cP2. True False Frank partial is a sessile dislocation. True False Edge dislocations can cross-slip to move to other slip planes. True False
a) With the molar masses of 22.99 and 35.45 g/mol respectively for sodium and chloride and the density 2.17 g/cm³, what would be the lattice parameter for the cubic unit cell? b) With incident neutron beam of 13.7 meV, what would be the scattering angle 20 for the (200) and (400) Bragg peak? c) After you have measured at the (200) Bragg peak, moving to the (400) Bragg peak, how much an angle you need to rotate the A20? How much an angle you need to rotate the Δω? d) After you have measured at the (200) Bragg peak, instead of moving to (400) now you want to measure (111) Bragg peak, what are the A20 and Ao? Assume that the (110) Bragg peak has been aligned in the horizontal scattering plane by the four-circle goniometer.
