Smallest repeating unit of crystal lattice
Webb4. The distance between atoms in a crystal are in a ~1-2 Å range, so waves with approximately this wavelength are required to explore the crystal structure. Using de Broglie law (λ = h/p), calculate the energies of (a) neutrons (m=1.675×10-24kg), (b) electrons (m=0.911×10-28kg) and (c) X-rays required for the structural studies? 2 2 2; 2 Webb(Sometimes people say it’s the “smallest” repeating portion of the crystal, but that’s not true–see my article about primitive cells). The unit cell shows the lattice and basis. For example, here is a diamond cubic unit cell: This unit cell has an FCC Bravais lattice, but with a 2-atom basis.
