摘要：

The quantum mechanical phase shift for a massive particle due to gravity has been observed in a series of neutron interferometry experiments using perfect crystal silicon interferometers. While the results of these measurements are in qualitative agreement with the predictions of non-relativistic quantum mechanics and Newtonian gravity, there remains a very significant discrepancy between theory and experiment. It has been suggested that this discrepancy is due to a systematic effect related to the elastic deformation of the monolithic interferometer. In this work we describe X-ray measurements which indicate that such a systematic effect was overlooked in previous measurements. We conclude that the magnitude of these effects is sufficiently large to account for the current discrepancy between theory and experiment.
