dc.description.abstract Substituted Mn centers were studied in BaF2 and SrF2 crystals for possible off-center character. The angular dependence of the EPR spectra on the magnetic field direction was obtained at 1.3K and 4.2K in {11} crystal planes. Static electric fields up to 9 kV/cm were also applied along <111> and <1> at 4.2K and along <111> at 77K while taking EPR spectra. The EPR of SrF2:Mn++ was studied with similar electric fields along <111> directions at 4.2K. The splitting of EPR lines of a ruby crystal under an applied electric field demonstrated the experimental set-up functioned adequately. All spectra obtained for BaF2:Mn++ and SrF2:Mn++ showed no fine structure and were isotropic. The Mn appears to not be offcenter, but to have octahedral (h) site symmetry in these crystals.
