Abstract
The ground electronic state of the F center in CaF2 crystal, its optic al absorption energy, the activation energy of thermal diffusion and M center dissociation to pair of F centers are calculated using the Har tree-Fock embedded molecular cluster method. Different pseudopotential s, basis sets, boundary conditions and two computer codes, EMBED96 and Gaussian94, are employed and their results compared. (C) 1998 Elsevie r Science Ltd.
