Abstract
Starting from a many-body formulation that includes the phonon field, we develop a method of calculating the energy levels of an electron trapped at a defect in an ionic crystal. Detailed calculations for the $F$ center are given. The higher excited states of the $F$ center and the $K$ absorption bands are also discussed.
