We report an upper bound on parity-violating neutron spin rotation in He4. This experiment is the most sensitive search for neutron-weak optical activity yet performed and represents a significant advance in precision in comparison to past measurements in heavy nuclei. The experiment was performed at the NG-6 slow-neutron beamline at the National Institute of Standards and Technology (NIST) Center for Neutron Research. Our result for the neutron spin rotation angle per unit length in He4 is dφ/dz=[+1.7±9.1(stat.)±1. 4(sys.)]×10-7 rad/m. The statistical uncertainty is smaller than current estimates of the range of possible values of dφ/dz in n +4He. © 2011 American Physical Society.
