Linear dichroism in Ce 4V-core photoabsorption for CeRh.Bz with a hexagonalstructure is discussed on the basis of an impurity Anderson model. The model takesinto account the hybridization between the 4f orbit and conduction band states,multiplets arising from electrostatic interactions between electrons and crystallineanisotropy. In the paramagnetic state of the compound, the difference in themultiplet structure of 4d XAS is calculated between two incident beams with polarizations parallel and perpendicular to the c-axis with varying the crystalline field to increase the occupancy of the 4 f state with the azimuthal quantum number m = 0. Theresult shows that the dichroism is a promising characteristic to check recenttheoretical predictions on the occupancy of the 4f state with m=O in CeRh.B. andtherefore, to measure the crystal anisotropy.
