Phys. Rev. A 75, 055602 (2007) [4 pages]Reduced coherence in double-slit diffraction of neutronsReceived 2 August 2006; revised 29 March 2007; published 21 May 2007 In diffraction experiments with particle beams, several effects lead to a fringe visibility reduction of the interference pattern. We theoretically describe the intensity one can measure in a double-slit setup and compare the results with the experimental data obtained with cold neutrons. Our conclusion is that for cold neutrons the fringe visibility reduction is due not to decoherence, but to initial incoherence. © 2007 The American Physical Society URL:
