Nuclear Electromagnetic Moments

Nuclear Electromagnetic Moments. Electric Multipoles. The electric energy associated with the electric charge distribution in the nucleus is determined by the interaction of the nuclear charge distribution with electric fields. Parity of V n goes as (-1) n. QM Analog for the Nucleus.
