The \vec n + p \to d + \gamma experiment is a high-precision measurement of nuclear forces at low energies. We will measure the correlation between neutron spin and photon direction in the capture of cold neutrons on hydrogen. This correlation depends on the long-range component of the weak interaction between nucleons (protons and neutrons), and is particularly sensitive to the neutral weak current. The unique properties of the weak interaction allow it to be used to gain a better understanding of what is primarily a strongly-interacting system.
