A beam of 2.0-keV electrons incident on a crystal is refracted and observed (by transmission) on a screen 35 cm away. The radii of three concentric rings on the screen, all corresponding to fi rst-order diffraction, are 2.1 cm, 2.3 cm, and 3.2 cm. What is the lattice-plane spacing corresponding to each of the three rings?

A beam of X-rays of first-order wavelength 1.5406 Å is diffracted by a cubic crystal with lattice constant of 4.2 Å. What is the relationship between the glancing angle if the (002), (020), and (200) planes of the crystal diffract the X-ray? Given: (1) For a cubic crystal, the lattice translation vector (a) relates lattice spacing (d) and Miller indices (h k l) through the relation a? = d²(h? + k² + l²); (2) 1 Å = 10-1º m.

You are given a small bar of an unknown metal. You find the density of the metal to be 18.6 g/cm3. An x-yar diffraction experiment measures the edge of the face-centered cubic unit cell as 4.13 x 10-10m. Find the atomic weight (in g/mol) of this metal and assess its identity.
The structure factor defines the amount of scattering from the planes hkl in the direction e defined by Bragg's law and is given by: N Fnkl = 2f, (hkl) exp 2mi (hx + ky, + lz) J=1 where the unit cell in the crystal contains N atoms of which the jh atom has an atomic scattering factor, f(hkl) and fractional unit cell co-ordinates x, y, z;. Show clearly, that for a body-centred cubic (bcc) lattice, diffraction peaks will be systematically absent for all planes where (h+k+l) is odd and that diffraction peaks will occur for all planes where (h+k+1) is even. Note: exp (nrti) = +1 if n is even exp (nri) = -1 if n is odd
If the interplanar spacing of NaCl is 2.814x10-10 m, what is the predicted angle at which X-rays of wavelength 0.140 nm will be diffracted in a first-order maximum?
The first - order diffraction maximum is observed at 12.6° for a crystal having an interplanar spacing of 0.240 nm. How many other orders can be observed in the diffraction pattern, and at what angles do they appear? Why is there an upper limit to the number of observed orders?
When x - rays of wavelength of 0.129 nm are incident on the surface of a crystal having a structure similar to that of NaCl, a first - order maximum is observed at 8.15°. Calculate the interplanar spacing of the crystal based on this information.
Tungsten (W) crystallizes in cubic structure. The edge length of the unit cell of this crystal structure is a = 3.1648 Å. When the X-ray diffraction experiment is performed, scattering occurs from the following planes: (110), (200), (211), (220), (310), (222), (321), (400), (411), (420), (332), (431) Which of the x-rays scattered from the (110) and (200) planes has the greatest intensity? Hint: The intensity of the x-ray scattered from any atom decreases as the scattering angle increases. Also note that λ / 2d = sinθ.
