Figure 8
The relative deviation δd/d of the (111) interplanar spacing d in parts per million from the undistorted value at room temperature (see color scales at the right-hand corner of each figure) in the plane Z = +1 (top), Z = 0 (middle) and Z = −1 (bottom). The overall negative sign of δd/d results from the simulation of crystal cooling from room temperature by liquid nitrogen, which of course contracts the crystal. See the text of §4 for definitions of the Z planes. |
