Time Invariance Violating Nuclear Electric Octupole Moments
نویسندگان
چکیده
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 atomic electric dipole moment, and the magnitude of this effect is calculated. The contribution of a nuclear EOM to such a dipole moment is found, in most cases, to be smaller than that of other mechanisms of atomic electric dipole moment production.

Enhancement of nuclear Schiff moments and time reversal violation in atoms due to soft nuclear octupole vibrations
Parity and time invariance violating (P,T -odd) nuclear forces produce P,T -odd nuclear moments, for example, the nuclear Schiff moment. In turn, this moment can induce electric dipole moments (EDMs) in atoms. We estimate the contribution to the Schiff moment from the soft collective octupole vibrations existing in many heavy nuclei. Two possible mechanisms are considered, mixing of the ground ...
متن کاملCollective T- and P-odd electromagnetic moments in nuclei with octupole deformations.
Parity and time invariance violating forces produce collective Pand Todd moments in nuclei with static octupole deformation. Collective Schiff moment, electric octupole and dipole and also magnetic quadrupole appear due to the mixing of rotational levels of opposite parity and can exceed singleparticle moments by more than a factor of 100. This enhancement is due to two factors, the collective ...
متن کاملNuclear Schiff moment in nuclei with soft octupole and quadrupole vibrations
Nuclear forces violating parity and time reversal invariance (P,T -odd) produce P,T -odd nuclear moments, for example, the nuclear Schiff moment. In turn, this moment can induce the electric dipole moment in the atom. The nuclear Schiff moment is predicted to be enhanced in nuclei with static quadrupole and octupole deformation. The analogous suggestion of the enhanced contribution to the Schif...
متن کاملNuclear octupole correlations and the enhancement of atomic time-reversal violation
We examine the time-reversal-violating nuclear ‘‘Schiff moment’’ that induces electric dipole moments in atoms. After presenting a self-contained derivation of the form of the Schiff operator, we show that the distribution of Schiff strength, an important ingredient in the ground-state Schiff moment, is very different from the electric-dipole-strength distribution, with the Schiff moment receiv...
متن کاملM ar 2 00 2 Electric dipole moments of Hg , Xe , Rn , Ra , Pu , and TlF induced by the nuclear Schiff moment and limits on time - reversal violating interactions
We have calculated the atomic electric dipole moments (EDMs) induced in Hg, Xe, Rn, Ra, and Pu by their respective nuclear Schiff moments S. The results are (in units 10S(e fm)−1e cm): d(Hg) = −2.8, d(Xe) = 0.38, d(Rn) = 3.3, d(Ra) = −8.5, d(Pu) = −11. We have also calculated corrections to the parityand time-invariance-violating (P, T odd) spin-axis interaction constant in TlF. These results a...
