Total Fluorescence Yield from Magnetic Materials Using Circularly Polarized X-rays

摘要

The circular dichroic signal in the total cross-section for resonance-enhancedelectric dipole scattering is calculated by an analytic method. The finding is the same as that found, without approximations, for the dichroic signal in the attenuation coefficient. Thus, the finding supports the use of the total fluorescence yield as a method of measuring the information known to be in the coefficient. An ion with a half-filled valence shell is shown to be an exceptional case. For all cases, we give the angular dependence of the total cross-section, with respect to the direction of the primary radiation and the axis of quantization for the atomic states.
