Experiments performed in order to reveal fundamental differences between the diffraction and interference of waves and electrons

Diffraction patterns of electrons are believed to resemble those of electromagnetic waves (EMW). I performed a series of experiments invoked to show that the periodicity of peaks in the di raction diagram of electrons is concerned with the periodicity of the arrangement of scattering centers in the di raction grating in combination with the supposed character of the spatial structure of the electron as a system of regularly spaced concentric shells of elasticity. I started from the experiment on the di raction of electrons and EMWs at the sharp edge of the opaque half-plane. This simple scattering con guration enabled me to discriminate between the re-radiation mechanism of the wave di raction and ricochet scattering of electrons on the edge of the half-plane. Then I made experiments with scattering on composite objects proceeding step by step from a single straight edge to a couple of edges (one slit) and then to four edges (two slits). Thus I succeeded in interpretation of the doubleslit di raction (four straight edges) in terms of the scattering on a single edge. In favor of the elastic corpuscle mechanism of the electron's scattering there speak also following experiments made by me. The displacement of a one half-plane of the slit along the direction of the electron beam at a wave half-length does not virtually a ect the scattering diagram of electrons while the interference pattern of EMWs changes in this case from the positive to negative. On the other hand, the heating of the slits blurs and widens the scattering pattern of electrons but exerts no appreciable in uence on that of EMWs.
I succeeded also in the observation of the electron's trajectory. Equipping the slit's edge with a semiconductor sensors I registered the passing of the electron through the slit detecting simultaneously a weaker signal at another slit. This technique of observation of the event what slit did the electron pass through appeared not to destroy or disturb the "interference" pattern.
Closing one slit by inserting therein a transparent for EMWs piece of dielectric I have found that the scattering pattern beneath this slit vanishes while the scattering pattern under the open slit remains as before when both slits were open. This experiment indicates that the electron "interferes" with its electromagnetic component passed via the slit plugged by the transparent for it dielectric.
