Foldy–Wouthuysen transformation for a spinning particle with anomalous magnetic moment
A Barducci, R. Giachetti, Giulio Pettini
In this paper we study the Foldy–Wouthuysen transformation for a pseudoclassical particle with anomalous magnetic moment in an external classical 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 external magnetostatic fields. The explicit expressions of the diagonalized Hamiltonians are calculated.
