Experiments on Electron Bremsstrahlung When Passing Through Narrow Slits and Their Interpretation in Terms of Inverse Photoelectric Effect

Authors: V.V. Demjanov

          In special experiments on slowing down soft electrons from the energy E1 at the entry of a narrow slit down to E2<E1 in the exit there was drawn a conclusion that the source of the retardation radiation with the energy ΔE12=E1E2 in the opening of the narrow slit is not the passing by electrons, but a radiation due to inverse photoelectric effect of valence electrons in the stationary structure of the edge of the hole. Here we consider only central-axial flight of electrons via a narrow slit (of the width <0.2 μm) which generates quanta of light with the energy ΔE12. If with the aid of external electrodes inside a wider slit (>2 μm) to create a field with the same retardation potential φ=ΔE12 then despite of the same slowing down in it of central-axial flying by electrons there will be observed no emission of light quanta with the energy ΔE12. This enables us to interpret in a different way the mechanism of induced radiation of matter under quantum transitions in it of particles. It looks such that the flying by electrons excites around themselves spherical zones of nonlinearity with radius ∼ 0.2 μm. The orbitals (with energies E1 and E2<E1) of stationary valence electrons in the edge of the narrow orifice (of the width < 0.2 μm), falling in these zones, in accord with the Ritz combination rule gives from the difference of terms ν1=E1/h and ν2=E2/h the observed in experiments monochromatic radiation of the frequency ν121– ν2. The passing of center-axial electrons via a wider gaps (>2 μm) is not affected by the nonlinearity zones of the orbitals of stationary valence electrons in the edge of the slit. Thence, despite of the dragging by the external field of the diaphragm φ=ΔE12 in this case the flying by electrons does not radiate at the frequency ν12E12/h.
