Abstract : The purpose of the work was to calculate the electronic energy levels of the simplest of these models, the unassociated alkaline earth cation with one trapped electron. The problem is treated as a one-electron problem, and the solution is estimated by using one-parameter hydrogen-like trial wave functions in a variational procedure. The impurity cation is treated as a substitutional distributed charge, the distribution being determined from the statistical procedure of Thomas and Fermi. The host lattice is considered to be an essentially continuous dielectric medium, the only discontinuity being the spherical cavity in which the divalent cation is placed. Account is taken of the lattice polarization by using an effective dielectric constant that is a function of both the high- and low-frequency dielectric constants. (See also AD-415 999). (Author)
