Engineering Physics Annotation << Back A SIMPLE WAY OF INTRODUCTION AND INTERPRETATION OF THE PAULI THEOREM Z.Z. ALISULTANOV The Pauli principle is introduced in quantum mechanics as a feature of the wave function of the fermion system, which consists in changing the sign of this function under spatial inversion. This principle is a consequence of Pauli’s theorem on the connection between spin and statistics. At the same time, the physical mechanism of such a change remains a mystery and the direct connection of this with the spin of the particles. Therefore, this rule of nature is called a principle, and not a law. Here we propose a more graphic conclusion of the Pauli principle. This conclusion from the very beginning is connected with particle spin and is, in our opinion, simpler for primary perception. Thus, the result of this work is also methodical in nature. On the basis of these simple considerations, we consider not identical fermion and boson systems. It is shown that the symmetry of the wave function of a fermion pair in the general case is not a single-valued characteristic of a but depends on the specifi c values of the spins. A spatial analogue of the Kramers theorem for a system of fermion-boson pairs is introduced. Keywords: Pauli principle, spin, fermions and bosons, Kramers theorem.
