General dynamics of tensor polarization of particles and nuclei in external fields

Abstract

The tensor polarization of particles and nuclei becomes constant in the coordinate system rotating with the same angular velocity as the spin and rotates in the lab frame with the above angular velocity. The general equation defining the time dependence of the tensor polarization is derived. An explicit form of dynamics of this polarization is found in the case when the initial polarization is axially symmetric.
