| Abstract: | Based on the analysis of the experiment principle of the neutron interferometer in the gravitational field, the phase shift of two neutron beam in the double-slit experiment is studied through equivalent transformation by using path integral method. The obtained phase shift formula is different from that of Staudenmann et al. , but the physics meaning is consistent. Evenmore, the obtained formula is concise and give a more clear physics picture. |
