Manifestation of tensor polarizabilities of the deuteron in storage-ring experiments.
Alexander J. Silenko

The tensor electric and magnetic polarizabilities of the deuteron give important information about spin-dependent nuclear forces. If a resonant horizontal electric field acts on a deuteron beam circulating into a storage ring, the tensor electric polarizability stimulates the buildup of the vertical polarization of the deuteron (the Baryshevsky effect). The tensor magnetic polarizability of the deuteron causes the spin rotation with two frequencies and experiences beating. General formulas describing these effects have been derived. The problem of the influence of tensor polarizabilities on spin dynamics in a deuteron electric-dipole-moment experiment in storage rings has been investigated. Doubling the resonant frequency used in this experiment dramatically amplifies the Baryshevsky effect and provides the opportunity to make high-precision measurements of the deuteron's tensor electric polarizability. The tensor magnetic polarizability of the deuteron can be measured with the initially tensor polarized beam that can acquire a final horizontal vector polarization of order of 1%.
Key words: deuteron, tensor electric polarizability, tensor magnetic polarizability
