Spin oscillations and spin dichroism of deuterons rotating in a storage ring

It is shown that the Bargman-Myshel-Telegdy equation does not completely describe the evolution of deuteron spin characteristics in the storage ring, that's why the terms corresponding to the birefringence effect in a substance and both in pseudo electric and ordinary electric fields should be added to the Bargman-Myshel-Telegdy equation. The phenomenon of deuteron birefringence can imitate the spin rotation due to the EDM. The study of this effect also enables one to measure both the spin-dependent part of the amplitude of the coherent elastic scattering by the nuclei through zero angle and the tensor electric polarizability of a deuteron.
