摘要：

A new experimental approach in the determination of the neutron–electron interaction amplitude is proposed. The main idea of this approach is to use a perfect-crystal neutron interferometer as both a sample and a device for the measurement of the extra phase shift caused by the neutron interaction with atoms of Si. Indeed, such a sample (an interferometer blade) has a well-known atomic density and is á priori perfectly aligned with respect to the crystal lattice of the interferometer crystal. This results in the minimization of systematic errors caused by sample alignment and increases the overall experimental accuracy. Some theoretic estimations and details of an experimental setup are discussed.
