DIPOLE POLARISABILITY, OSCILLATOR STRENGTH an‎d MAGNETIC SUSCEPTIBILITY OF FLUORIDE ION IN FLUORIDE STRUCTURE CRYSTALS

A variational-perturbation approach is invoked to study the effect of the environment potential around Fluoride ion on some important electronic properties. The dipole polarisability α, oscillator strength S(-2) and S (-1) and magnetic susceptibility χ are theoretically estimated for Fluoride ion in different potentials. Also we calculate these electronic properties in many Fluoride structure crystals such as CdF2, CaF2, PbF2, SrF2 BaF2, and LiF.
