SCF-Xα -SW Calculations of Electron States in Rare Earth Ion Doped Crystals

The SCF-Xα-SW method has been applied to the calculations of electronic states in rare earth ion doped crystals. The conventional method is modified by use of a second Watson sphere. For Yb3+ and Tm2+ in CaF2, the crystal field parameters and transferred hyperfine interaction parameters have been calculated using this method. The agreement with experiment is reasonably good for the hyperfine interactions, but less good for crystal field interactions. This method is felt to be reasonably promising for calculations of rare earth electronic states but further work is necessary to refine the technique.
