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.
