Abstract
A search for permanent electric dipole moment of atoms has yielded the null result dHg)=(0.7±1.5)× e⋅cm, which improves by an order of magnitude the limits on several possible interactions that violate time-reversal symmetry. The experiment was performed by the use of optically pumped atomic oscillators to measure any shift in the NMR frequency of (I=(1/2) produced by an external electric field.
