Spin is not a Moment of Momentum

Authors: Radi I. Khrapko

Unambiguous definitions of energy-momentum and spin tensors are cited. It is shown that moment of momentum (i.e. angular momentum) and spin are different concepts, but spin is absent in the modern classical electrodynamics. Nevertheless, angular momentum and spin of a rotating dipole radiation is calculated. We notice Jackson’s and Becker’s mistakes, which convinced them of the similarity between spin and angular momentum, and we show that the equality between these concepts is false.
