Coherence and spectral filtering in neutron interferometry
H Kaiser, R Clothier, SA Werner, H Rauch, H Wölwitsch - Physical Review A, 1992 - APS
The coherence length of a neutron wave packet depends on the spectral width of the
distribution of wave vectors that make up the packet. The coherent overlap of the wave packets …
