Abstract

The birefringence effect in the nuclear pseudoelectric field of matter and an external electric field for a particle (deuteron, nucleus) moving in a storage ring is discussed. The influence of the birefringence effect on the EDM measurement experiments is considered. The attention is drawn to the possibility to measure the spin-dependent amplitude of the elastic coherent scattering of a deuteron by a nucleus, the electric polarizability of a deuteron (nucleus). Using a gas target with polarized nuclei also allows to study P-,T-odd interactions.
