T-violation and neutron optics experiments

It is shown that a two-step model of the reaction pd→³HeX (X=η, η′ eω, φ), involving the subprocesses pp) →dπ⁺ and π⁺ n→Xp, can account for the form of the energy dependence of experimental cross sections above the thresholds under the assumption that the singlet part of the pp→dπ⁺ amplitude dominates. The spin-spin asymmetry for the reaction dp→³HeX has been found to be ∼;−1 in the forward-backward approximation. Pis’ma Zh. éksp. Teor.
