What is Optical Anisotropy of MgF, in Its UV Absorption Region about?

## Abstract Reflectance measurements are used to calculate the ordinary and extraordinary optical constants of an anisotropic MgFz crystal in the energy range 11 to 28 eV. Partially linearly polarized light is used and a method of least squares is employed to compute the results. An excitonic splitting of 0.5 eV is observed at the r point. The anisotropy of the forbidden gap is 0.2 eV while that of plasmon is 0.3 eV. A tentative interpretation is given based upon a symmetry group analysis at the T point.
