Neutron spin rotation in $$\vec{n}$$-$$d$ scattering
The neutron spin rotation induced by parity-violating (PV) components in the nucleon-nucleon potential is studied in $$\vec{n}$$-$$d$ scattering at zero energy. Results are obtained corresponding to the Argonne $$v_{18}$$ two-nucleon and Urbana-IX three-nucleon strong-interaction potentials in combination with either the DDH or pionless EFT model for the weak-interaction potential. We find that this observable is dominated by the contribution of the long-range part of the PV potential associated with pion exchange. Thus its measurement could provide a further constraint, complementary to that coming from measurements of the photon asymmetry in $$\vec{n}$$-$$p$ radiative capture, on the strength of this component of the hadronic weak interaction.
