Description
Using an Ashcroft empty-core model pseudopotential, we have calculated the binding energy of the intermediate structures between b.c.c. and f.c.c. sodium at zero temperature for two homogeneous-deformation reaction-path models, namely those of Bain (1924) and Zener (1948). Bain's model gives a lower barrier energy than that of Zener: 9.2 K per atom, much lower than a previous estimate based on the second-order elastic constants. (author)
