熱散漫散乱

thermal diffuse scattering, TDS

[目次：理論(電子の散乱／回折／結像)]

試料への入射電子が原子の熱振動(格子振動)を励起する非弾性散乱をいう。この非弾性散乱はエネルギーの損失が小さいので(0.1eV以下)、準弾性散乱と呼ぶこともある。

"Thermal diffuse scattering" is inelastic scattering where the incident electrons on the specimen excite thermal vibrations (lattice vibrations) of atoms in the specimen and scattered in a diffuse manner. Since this scattering loses only a small energy (0.1 eV or less), this is often called quasi-elastic scattering.
