The physical mechanism of single slit diffraction

Jiaqing Yan

The mainstream quantum mechanics uses “probability wave superposition and single-electron self-interference” to explain electron single-slit and double-slit diffraction. This theory deviates from the essential nature of real particle interactions and has fundamental logical flaws. The electron is a negatively charged real particle with a definite physical size and high-frequency transverse oscillation; a single real particle has no physical basis for self-interference. Abandoning the abstract probability wave hypothesis, this paper establishes a complete real-interaction model including electrostatic repulsion deflection, surface electron exchange, collision scattering, microscopic refraction, and barrier diffraction, based on the three-dimensional random transverse oscillation and charge repulsion of electrons. The model uniformly explains the real formation mechanism of electron single-slit diffraction and double-slit interference fringes. This paper proves that in single-electron sequential emission, each electron passes through only one slit; all bright and dark fringes are the statistical result of multiple microscopic interactions between electrons and slit walls or the central barrier. The disappearance of fringes under observation is caused by external disturbance to the inherent oscillation and wall-interaction equilibrium, not by wave function collapse. This paper further clarifies that whether an electron can pass through a slit is determined by its transverse oscillation amplitude, not by wavelength. Amplitude directly corresponds to slit width and is the core controlling variable of diffraction. Meanwhile, if no slit is placed, electrons flying directly to the screen produce no diffraction or interference fringes, proving that electrons themselves have no self-interference ability. Fringes are generated by slit structures, not by intrinsic wave interference of electrons. This study corrects the century-long misunderstanding of electron diffraction and establishes a new microscopic diffraction mechanism consistent with classical real-particle physics.

Phenomena of electron, neutron, atomic and molecular diffraction have been studied in many experiments, and these experiments are explained by many theoretical works. We study neutron single-slit diffraction with a quantum mechanical approach. It is found that the obvious diffraction patterns can be obtained when the single-slit width a is in the range of 3λ~60λ. We also find a new quantum effect of the thickness of single-slit which can make a large impact on the diffraction pattern. The new quantum effect predicted in our work can be tested by the neutron single-slit diffraction experiment.

We studied electron single-slit,double-slit and three-slit diffraction with a new quantum mechanics approach and obtained the following results.(1) For single-slit diffraction,the thickness of the single-slit can make a large impact on the diffraction intensity and pattern.(2) For double-slit diffraction,when the ratio of(a+d)/a=n(n=1,2,3,…),orders n,2n,3n,… are missing in diffraction pattern,when the ratio of(a+d)/a≠n(n=1,2,3,…),there isn't missing order in diffraction pattern.(3) For double-slit diffraction,it can be found that when the thickness of the double-slit increases,the diffraction intensity and pattern will be changed,and when the thickness of the double-slit increases,the missing order phenomena disappear.(4) For three-slit diffraction,when the thickness of the slit increases,the diffraction intensity and pattern will be changed,and there is one secondary maxima and two minima between the two principle maxima.
