Energy of ordering in alloys of Mg—In and Mg—Cd, calculation using the pseudopotential approximation and comparison with experiment

The ordering energy is computed by means of the pseudopotential method for Mg-In and Mg-Cd alloys. The computation results are compared to the ordering energy determined from diffuse scattering of X - rays. Over significant concentration intervals, the theoretical and experimental values of the ordering energy for the first coordination sphere are close in magnitude.
