在非惯性系中进行的中子干涉测量基本上受到干涉仪晶体中发生的动态衍射效应的影响，这一点迄今尚未得到考虑。我们已经发展了一个相应的理论，从中可以得到一个修正的相移，同样适用于在重力影响下或在加速中子干涉仪上进行的干涉测量。该理论还预测，与科莱拉-奥弗豪斯-维尔纳重力实验中观察到的加速度增加相比，干涉会逐渐减弱，但无法明确解释。
Neutron interferometry performed in a noninertial frame is essentially influenced by dynamical diffraction effects occurring in the interferometer crystal which hitherto have not been taken into account. We have developed a corresponding theory from which a corrected phase shift is obtained which applies likewise to interferometry performed under the influence of gravity or on an accelerated neutron interferometer. The theory also predicts fading of interference contrast with increasing acceleration as was observed in the Colella-Overhauser-Werner gravity experiments but could not be explained unambiguously.
