Weak interactions between u and d quarks induce weak interactions between nucleons. These weak-interaction effects can be isolated from strong interactions using parity-violation (PV). The nucleon-nucleon (NN) weak interaction amplitudes are constrained by neither theory nor experiment. We describe a proposed measurement of PV neutron spin rotation in liquid helium {phi}PV(n,{alpha}) that is scheduled to run in 2006 with a sensitivity of 3x10-7 rad/m.
