New measurement of the electric dipole moment of the neutron

Abstract A new experiment on the search for the electric dipole moment of the neutron was carried out using a magnetic resonance set-up with electric field and stored ultracold neutrons. The EDM of the neutron was measured to be +(2.6±4.2±1.6)×10 −26 e cm, the first error being RMS or statistical and the second one systematical. An upper limit at the 95% CL is | d n | −26 e cm.
