The polarization energy of a complex is calculated for all alkali halides crystals containing Eu ++ impurities. Up to 48 nearest neighbors of the complex are considered, and assumed that the field on each dipole is the one produced by the charge of the complex and by the field produced by the other induced dipoles. The results show that there are no significant changes in all alkali halides when going from second to fourth‐order. Therefore, it is not necessary to take into account a large number of neighbors when calculating the polarization energy. This is a very important result since a low symmetry defect is considered.
