摘要：

We propose Lagrangian formulation for the particle with value of spin fixed within the classical theory.The Lagrangian is invariant under non-Abelian group of local symmet ries.On this reason,all the initial spin variables turn out to be unobservable quantities. As the gauge-invariant variables for description of spin we can take either the Frenkel tensor or the Bargmann-Michel-Telegdi(BMT) vector. Fixation of spin within the class icaltheory impliesO(h ($) over bar)-corrections to the corresponding equations of motion.
