Diamond crystal reflectivity for X-rays in two successive 800 Bragg reflections calculated as a function of photon energy E with a central energy, E0 = 14.4125 keV, corresponding to the nuclear resonance of 57Fe. The Bragg angle is θ = 74.7207°. The photon energy dependences are calculated for two possible X-ray polarization states, π and σ. |
