Résumé : The method developed in a recent paper by the authors and R. Bingen is extended to real three dimensional lattices. The zero point energy is calculated for isotopic mixtures and pure isotopes. The results obtained for one dimensional lattices are shown to remain qualitatively valid for three dimensional lattices; however, the heat of mixing is smaller than in the one-dimensional case. The stable state at 0°K always requires a separation into pure isotopes. © 1954 Stichting Physica, Amsterdam, Nederland.
