Neutron interferometry

DEC 01, 1980

Coherent beams of neutrons, split and recombined by Bragg diffraction in a perfect single crystal of silicon, demonstrate effects on the phase of the wavefunction due to gravity and other phenomena.

Diffraction effects at wavelengths on the order of angstroms have been known since Max von Laue’s demonstrations of x‐ray diffraction in 1912. Interference between well‐separated, coherent beams, however, is much more difficult to arrange.
