emiT is an experiment to test a fundamental symmetry, T-invariance, by measuring the correlations between the neutron spin and the momenta of the electron and proton. A measurement at the NIST cold neutron facility in Gaithersburg, MD, was completed in 1997, and a second is to take place in 2001 with an extensively upgraded apparatus.
For a brief overview of the current status of emiT see the current NPL Annual Report.
