Nuclear anapole moments
Nuclear anapole moments are parity-odd, time-reversal-even E1 moments of the electromagnetic current operator. Although the existence of this moment was recognized theoretically soon after the discovery of parity nonconservation ~PNC!, its experimental isolation was achieved only recently, when a new level of precision was reached in a measurement of the hyperfine dependence of atomic PNC in Cs...
متن کاملNuclear magnetic quadrupole moments in the single-particle approximation.
Static magnetic quadrupole moment of a nucleus, induced by T-and P-odd nucleon-nucleon interaction, is investigated in the single-particle approximation. Models are considered allowing for analytical solution. The problem is also treated numerically in a Woods-Saxon potential with spin-orbit interaction. The stability of results is discussed.
متن کاملNuclear Anapole Moments and the Parity-nonconserving Nuclear Interaction
The anapole moment is a parity-odd and time-reversal-even electromagnetic moment. Although it was conjectured shortly after the discovery of parity nonconservation, its existence has not been confirmed until recently in heavy nuclear systems, which are known to be the suitable laboratories because of the manybody enhancement. By carefully identifying the nuclear-spin-dependent atomic parity non...
