Unformatted text preview: | s (0) | 2 of a crystal atom about its equilibrium position. Look up the atomic mass, elastic constants, and melting temperature T M of Ag, and estimate | s (0) | 2 at T = 0 and T = T M . 3. Calculate the dispersion of a simple linear chain of atoms each of mass M , bound together with springs of spring constant f . Now, reconsider the example of a diatomic linear chain discussed in Ibach and Luth Sec. 4.3. Show that when M = m for the latter example, the two results are consistent ( hint remember that when M = m that the principle translation distance halves). 1...
