本文计算了单能（平面波）中子束通过由宽度随时间变化的狭缝组成的斩波器所产生的随时间变化的波函数和能谱。观察预测的效果的实验可能性进行了讨论。本文提出了一种新型的非弹性散射谱仪，它采用了飞行时间仪器中的帧重叠技术。
We calculate the time dependent wave function and energy spectrum resulting from the passage of a monoenergetic (plane wave) neutron beam through a chopper consisting of a slit with time dependent width. Experimental possibilities of observing the predicted effects are discussed. A new type of inelastic scattering spectrometer involving the use of frame overlap in a time of flight instrument is proposed.
