Nuclear Moments
Spins, electromagnetic moments and radii are basic observables characterizing a particular nucleus. We review a variety of experimental techniques currently used to measure these quantities for unstable nuclei far from stability and for isomeric nuclear states. The experiments can be traced back to two different principles: Optical high-resolution spectroscopy reveals the interaction between nu...
متن کاملNuclear 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 Bag Model and Nuclear Magnetic Moments
In 1991, we proposed a model in which nucleus is=20 treated as a spherical symmetric MIT bag and nucleon satisfies the MIT bag model boundary condition. The model was employed to calculate=20 nuclear magnetic moments. The results are in good agreement with=20 experiment data. Now, we found this model is still interesting and=20 illuminating. ∗Email:[email protected]
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...
متن کاملTime Invariance Violating Nuclear Electric Octupole Moments
The existence of a nuclear electric octupole moment (EOM) requires both parity and time invariance violation. The EOMs of odd Z nuclei that are induced by a particular Tand P-odd interaction are calculated. We compare such octupole moments with the collective EOMs that can occur in nuclei having a static octupole deformation. A nuclear EOM can induce a parity and time invariance violating atomi...
