• As a preliminary, we express the energy increase of an ionic crystal due to arbitrary polarization in quadratic forms of two parts of polarization from the stand-point of dielectric continuum. Using this formulation we investigate how to solve the motion of an additive electron in an ionic crystal under the interaction with the polarization which the electron produces around itself, especially in the case when there is a trapping potential. We show that one is led to the usual method of treating such problems suggested by Mott and Gurney, when one uses the adiabatic approximation (in the sense of Born and Oppenheimer) for the system of an additive and the crystal electrons. On the other hand, if we proceed on the Hartree's approximation for the system, another method of treating these problems is obtained. The latter method is applied to the calculation of various thermal and optical energies of the F- and F'-centers, conduction electrons and polarons, with a simplified model. The essential aspects of this method are stressed in the last section.
