Bargmann-Michel-Telegi equation for the spin precession

The treatment of the BMT equation for spin precession has been programmed. Let be the polarization defined by a normed vector with 3 components P (each component taking a value between -1 and +1) The BMT precession equation is the following :

The gyromagnetic anomaly a is normally equal to α/2π +O(α^{2), α being the fine structure constant. With a strong field a is a function of the foeld strenght, through the parameter :}
