Neutron electric dipole moment

ID: neutron-electric-dipole-moment

The neutron electric dipole moment (nEDM) is a measure of the distribution of electric charge within a neutron. In quantum mechanics, particles with an electric dipole moment have a separation of positive and negative charge in their structure, leading to a non-zero value for the electric dipole moment, which would indicate a departure from perfect symmetry under time reversal and parity transformations (T and P violation).
