摘要：

X-ray absorption spectroscopy (XAS) has proved a powerful tool to investigate the local geometry around transition metal impurities in crystals. However, the measurement of XAS in single-crystals is made difficult because of the presence of very strong diffraction peaks (glitches). Recently, a new measurement method was proposed to investigate natural circular dichroism in the X-ray range [1]. The method here is adapted to the measurement of linear dichroism. We show how isotropic spectra and linear dichroism can be extracted from the angular dependence of XAS. As an example, we present the K-edge spectrum of chromium in ruby.
