Figure 4. Pair-correlation functions for Be-Be (black), O-O (red) and Be-O (blue) along the isochore of 12.257 ų/f.u. for the ZB phase.

The atomic structure, where Be and O atoms are denoted by red and green balls, respectively, is also provided in the insets. The corresponding initial kinetic energy is (a) 10000 K; (b) 11300 K; (c) 13000 K; and (d) 13500 K.
