Magnetic Dipole Sum Rules for Odd Nuclei

چکیده
Sum rules for the totaland scissors-mode M1 strength in odd-A nuclei are derived within the single-j interacting boson-fermion model. We discuss the physical content and geometric interpretation of these sum rules and apply them to Er and Dy. We find consistency with the former measurements but not with the latter. 21.60.Fw, 21.10.Re, 23.20.-g, 27.70.+q Typeset using REVTEX 1 The orbital magnetic dipole scissors mode [1] has by now been established experimentally as a general phenomena in deformed even-even nuclei [2]. The M1 strength systematics and deformation dependence have been extensively measured and corroborated in a variety of sum rules [3,4]. Within the interacting boson model (IBM) [5], a sum rule [3] has related this strength to the number of quadrupole bosons in the ground state of the even-even target nucleus, 〈0|Nd|0〉,

متن کاملThe Theta Term in QCD Sum Rules and the Electric Dipole Moment of the Vector Meson
We demonstrate that the QCD sum rule method can be successfully applied to the calculation of CP-odd electromagnetic observables induced by a vacuum θ–angle. We implement the approach in calculating the electric dipole moment of the rho meson to ∼ 30% precision, and find that the result can also be explicitly related to the vacuum topological susceptibility.

متن کاملHadron Electric Dipole Moments from CP-Odd Operators of Dimension Five Via QCD Sum Rules: The Vector Meson
We present a complete analysis of the electric dipole moment (EDM) of the ρ-meson induced by CP violating operators of dimension 4 and 5 within the QCD sum rules approach. The set of CP-odd operators includes the theta term and the electric and chromoelectric dipole moments of the three light quarks. We find that the ρ-meson EDM induced purely by the EDMs of quarks is smaller, but still in reas...
متن کاملMagnetic dipole moment of the light tensor mesons in light cone QCD sum rules
The magnetic dipole moments of the light tensor mesons f2, a2 and strange K∗0 2 (1430) tensor meson are calculated in the framework of the light cone QCD sum rules. It is observed that the values of the magnetic dipole moment for the charged tensor particles are considerably different from zero. These values are very close to zero for the light neutral f2 and a2 tensor mesons, while it has a sm...
متن کاملMagnetic Dipole, Electric Quadrupole and Magnetic Octupole Moments of the ∆ Baryons in Light Cone QCD Sum Rules
Due to the very short life time of the ∆ baryons, a direct measurement on the electromagnetic moments of these systems is almost impossible in the experiment and can only be done indirectly. Although only for the magnetic dipole moment of ∆++ system there is some experimental data, the theoretical, phenomenological and lattice calculations could play crucial role. In present work, by calculatin...
