摘要：

The results of a new neutron gravitation experiment are reported. The change in the energy of a neutron falling to a known height in the Earth's gravitational field is compensated by an energy quantum h Omega transferred to the neutron as a result of the phase modulation of the neutron wave. A phase diffraction grating moving across the direction of the propagation of the neutron wave is used as a modulator. The experiment has been carried out with ultracold neutrons Interference filters, neutron analogues of Fabry-Perot interferometers, are used for the spectrometry of ultracold neutrons. The force m (g) g (n) acting on the neutron in the Earth's gravitational field has been measured with an accuracy of about 0.2%.
