Phys. Rev. C 78, 014002 (2008) [8 pages]Neutron spin rotation in n⃗-d scatteringSee Also: Erratum Received 23 May 2008; published 15 July 2008 The neutron spin rotation induced by parity-violating (PV) components in the nucleon-nucleon potential is studied in n⃗-d scattering at zero energy. Results are obtained corresponding to the Argonne v18 two-nucleon and Urbana-IX three-nucleon strong-interaction potentials in combination with either the Desplanques-Donoghue-Holstein or pionless effective field theory models 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 n⃗-p radiative capture, on the strength of this component of the hadronic weak interaction. © 2008 The American Physical Society URL:
