Effects of Lattice Vibrations on Dynamical Diffraction of Electron and X-Rays

抄録

The temperature dependence of the generalized scattering factor corrected for inelastic excitations in the crystal is studied theoretically for dynamical diffraction of X-rays and electrons. It is shown that the generalized scattering factors Φ_h=\varphi_h+C_h0 for X-ray diffraction and χ_h=V_h+C_h0(Y) for electron diffraction (C_h0 and C_h0(Y) are parts due to inelastic electronic excitations, respectively) are modified by the usual Debye-Waller factor, when the thermal motion is described with rigid-ion model and Einstein model.
