The angular frequency of vibrations in a one-dimensional monatomic crystal are given byω(k) = squareroot(4κ/m) l sin (ka/2) l,wherek = 2π/λis the wavenumber of the vibration pattern in terms of its wavelength λ, κ the spring constantbetween neighbouring atoms, and m the mass of each atom.(i) Show that the frequency does not change if one shiftsk → k + 2π/a(ii) Briefly explain the physical reason for this periodicity
Problem 35-28: What is the ground-state energy in electron volts of 10 noninteracting fermions each with a mass of 5.02E-27 kg in a one- dimensional box of length L 3.90E-10 m ? (Because the quantum number associated with spin can have two values, each spatial = state can hold two fermions.) 0.044 eV
The vanadium crystallizes in the body centered cubic lattice with a lattice parameter a. The X-ray diffraction data were collected from this compound and the following first four Bragg positions 20 (degrees): 21.06, 30.17, 37.03 and 43.10 were registered. The wavelength of the used X-ray radiation is 2 = 1.54Á. 1- Give the Bragg's Law. 2- Determine the inter-planer spacing d of the family of lattice planes (hke) of the cubic system. hkt 3 - Using the structure factor, determine the allowed reflections of the body centered cubic. 4- Index the four Bragg angles given above and calculate the cell parameter a.
