25. 3 prevents us from more quantitative discussion. The apparent modulation of the scattering intensity may include the modulation in X-ray absorption. However, the modulation of X-ray absorption due to the X-ray nonreciprocal directional dichroism should be dependent on the scattering angle as cos θ, and hence the modulation in X-ray absorption alone cannot explain the larger resonant enhancement in the (040) MXS.
