Neutron electric dipole moment information


The neutron electric dipole moment (nEDM), denoted dn, is a measure for the distribution of positive and negative charge inside the neutron. A nonzero electric dipole moment can only exist if the centers of the negative and positive charge distribution inside the particle do not coincide. So far, no neutron EDM has been found. The current best measured limit for dn is (0.0±1.1)×10−26 e⋅cm.[1]
