a. If a Bragg angle of 41.31^o 2-theta is observed for a first order peak from a {110} plane in a pure BCC element using Cu K-alpha radiation (1.54 A wavelength), what is the interplanar spacing of the {110} planes in this material?

b. What is lattice parameter of this element based on this peak?

c. If the density were measured to be 5.8 g/ml, how could you use the lattice parameter value calcuated in part B to determine which element this is using only a perodic table.

*Bragg Scattering What is the Bragg Scattering angle (i.e. the angle, in degrees, between the incoming incident beam and the reflected beam) for electrons scattered from a nickel crystal if their energy is 63 eV? The spacing between Ni Bragg planes is 0.215 nm. Give your result to 3 significant figures.
