Charged Particle Diffraction at the Edge of a Ring of Neutral Gold Atoms

Abstract

A scattering model describing the interaction between charged particles and a set of rigid neutral atoms was developed to demonstrate that particle theory could predict charged particles diffraction in materials composed of neutral atoms. A ring of gold atoms with a planar distribution of atomic electrons was used as the target. Electrons, positrons, neutrons, anti-neutrons and photons showed theoretical evidence of diffraction. The results of the calculations show signs of Poisson-Arago spot formation with spot not only behind the ring but also in front of it and these spots appeared independently of the projectile charge. This finding agrees with wave and quantum mechanics theory but the fact that a deflection at the edge of a ring of atoms is obtained using classical electrostatics and a quasi-quantum mechanical model for the atomic electrons, indicates that the wave (quantum) theory is not necessary to explain diffraction and if we take into account that the wave theory cannot explain the black body radiation, neither the photoelectric effect and nor the Compton effect, then the particle theory of diffraction is put in a strong solid grounds. Due to the importance of this matter in theoretical physic and gravitation, it is worthy to implement simulating conditions (using full size modeling) to compare the results with experimental data.
