A performed in 1940 experiment contradicts the above calculations. H. Boersch get the deflection of 34 ekV-electrons on an edge. The lateral dimension of the beam was 140 Å, the distance to the edge 0,35 mm and the distance to the observation screen was 330 mm and the distance between maxima about 20 μm.

I wrote about electron diffraction in this non published paper (German)

edit: Since for electron beam welding we need a vacuum to prevent the dissipation of the beam, it seems not very practicable to get results in a bubble chamber.

How to manage it, if a performed experiment contradicts the calculations? H. Boersch get the deflection of 34 ekV-electrons on an edge.
