| 摘 要： | 利用同步辐射光，在对称Ｌａｕｅ情况下，于Ｇａ的Ｋ吸收限附近，测定了ＧａＡｓ（２００）的衍射波和透射波的摇摆曲线．通过测定的透射波的摇摆曲线和Ｘ射线衍射动力学理论的相应计算结果的定量比较，求得ＧａＡｓ中的Ｇａ原子在其Ｋ吸收限附近的反常散射因数

| Abstract: | The diffracted and the transmitted rocking curves for GaAs(200) in the symmetric Laue case are observed near the Ga K-absorption edge by using the synchrotron radiation. The quantitative comparison between the measured transmitted rocking curves and the corresponding calculated ones based on the dynamical theory of X-ray diffraction has been cattied out, and the anomalous scattering factors for Ga K-absorption edge in GaAs have been determined. |
