摘要：

We present atomic calculations of the magnetic dichroism in 4d and 5d x-ray-absorption (XAS) spectra of trivalent actinide ions. The calculations are carried out for both linearly and circularly polarized light at zero temperature. Large magnetic dichroism is predicted for 5d XAS with polarization-dependent spectral shape and intensity. For 4d XAS the spectral shape is less polarization dependent, but the branching ratio is expected to be very sensitive to solid-state effects.
