Abstract

In the present paper, we derive the exact solution of the BMT equation for the spin rotation of relativistic negatively charged particles passing through a thin bent crystal in the regime of planar channeling. It is shown that during the passage through the crystal a particle polarization vector oscillates. If one takes into account, the energy and angular divergence of the initial particle beam these oscillations die fast with particle penetration length into a crystal, and particle spin rotation is determined by the crystal bending angle.
