Abstract
The mean-square amplitudes and mean-square velocities of vibration have been calculated for the (100) surface of NaCl with the Kellermann rigid-ion model. The calculated value of (the direction being perpendicular to the surface) is only about 1.6 at high temperatures, as compared with calculated and experimental values ranging upward from about 2.0 for monatomic metals and noble-gas solids.
