An empirical expression for a short range three body interaction in a lattice is suggested which leads to the same force constants as obtained by Basu and Sengupta from the consideration of deformability of the ions. Introducing this additional interaction, the stability of the cesium halide crystals is investigated. The stability is found to be correctly predicted in all cases.RésuméOn suggère une expression empirique représentant l'action réciproque de trois corps à petite distance dans un treillis qui mène aux mêmes constantes de force comme obtenues par Basu et Sengupta en considérant la déformabilité des ions. Comme introduction à cette action réciproque supplémentaire, on examine la stabilité des cristaux d'halite de césium. On s'aperçoit que la stabilité a été correctement prévue dans tous les cas.
