The Connection between Spin and Statistics in Quantum Mechanics

Abstract
We challenge the traditional explanation of the quantum mechanical Spin-Statistics Theorem based on field theory. Specifically, we demonstrate that the exchange of two identical particles can be carried out by spacial rotations, which multiply the two-particle probability amplitude by a phase factor that is either +1 or -1 depending on whether the particles have integer or half-integer spins. From this it can be concluded that the con- nection between spin and particle exchange in explained in the most fundamental way by the intimate connection between the spin operator and the generator of a rotation.
