Abstract

Dynamical diffraction theory applicable to both elastic and inelastic interactions of neutrons with crystals is rederived from the time-dependent Schrödinger equation. The description of satellite reflections, neutron acoustic resonance as well as the time modulation of integrated reflecting power in the case of slowly vibrating crystals are then dealt with using appropriate simplifications of the fundamental equations. The predictions of the theory are confronted with existing experimental results.

振动晶体的中子衍射
动态衍射理论适用于弹性和非弹性中子与晶体的相互作用是重新导出的时间依赖Schrödinger方程。然后对基本方程进行适当的简化,讨论了慢振动晶体的卫星反射、中子声共振以及积分反射功率的时间调制。理论的预测与现有的实验结果相矛盾。
