... slit. The vertical extension of the beam at the detector is determined by two factors, first the width a of the slit, and second the diffraction of the neutron beam by the slit. We recall that the ... What is the corresponding width of the beam on the detector? 5.1.3. In the actual experiment, the chosen value is a =5µm. What is the observed width of the beam at...
