| 摘 要： | 在四圆中子衍射仪上对α-碘酸锂单晶在外加直流电场作用下的中子衍射强度增大和各向异性作了系统的测定。对测定结果的分析表明:在场强不大时,衍射的增强及其各向异性可以用经典的各向异性消光理论得到较好的说明。

| Abstract: | The strong anisotropy of the neutron diffraction intensity enhancement effect observed in α-LiIO3 single crystal under dc voltage was investigated systematically with a 4-circle neutron diffractometer. Analysis of the result shows that both the enhancement and its anisotropy can be explained in the framework of the classical neutron diffraction extinction theorey only if the applied dc voltage is low enough. |
