Foldy–Wouthuysen transformation for a spinning particle with anomalous magnetic moment

In this paper we study the Foldy Wouthuysen transformation for a pseudoclassical particle with anomalous magnetic moment in an external, stationary electromagnetic field. We show that the transformation can be expressed in a closed form for neutral particles in purely electrostatic fields and for neutral and charged particles in exter- nal magnetostatic fields. The explicit expressions of the diagonalized Hamiltonians are calculated.
