Abstract —The structure of a stable and a superheated sodium crystal (including a failing one) is studied in a molecular-dynamics model. The radial distribution function of the bcc crystal differs in shape only insignificantly from that of liquid sodium. Variations in the structure of the crystal with increasing temperature are angle distribution of the nearest geometrical neighbors and the abrupt decrease in the number of polyhedral of the cuboctahedron-type point to a complete disorder in the bcc crystal.
