Polarization measurements on a magnetic quadrupole line in Ne-like barium.

چکیده
We have measured the absolute polarization of the 2p S022p (P3/2 o )3s@3/2#2 o magnetic quadrupole transition in Ne-like barium, excited in an electron-beam ion trap at a variety of energies. We find strong evidence for the existence of resonant excitation processes that are not explained by our collisional-radiative calculations even when the polarization arising from impact excitation is included. At energies well away from where the resonances occur, the agreement between experiment and theory is good. @S1050-2947~96!06208-7#

Electric-dipole, electric-quadrupole, magnetic-dipole, and magnetic-quadrupole transitions in the neon isoelectronic sequence
Excitation energies for 2l23l8 hole-particle states of Ne-like ions are determined to second order in relativistic many-body perturbation theory ~MBPT!. Reduced matrix elements, line strengths, and transition rates are calculated for electric-dipole (E1), magnetic-quadrupole (E2), magnetic-dipole (M1), and magneticquadrupole (M2) transitions in Ne-like ions with nuclear charges ranging from Z51...
متن کاملWhere Has All the Polarization Gone?
Circumnuclear tori are a central ingredient in the unification of the AGN phenomenon, but the conditions in the tori, the jet collimation, and the accretion mechanisms are still poorly constrained. Magnetic fields are involved in jet collimation and probably in feeding material into the nucleus, but those that are derived using equipartition are uncertain since equipartition conditions are not ...
متن کاملCompositional dependence of hyperfi ne interactions and magnetoelectric coupling in (BiFeO3)x-(BaTiO3)1–x solid solutions
The promise of coupling between magnetization and electric polarization and the potential to manipulate one through the other has become in recent years a driving force for many experimental works on multiferroic materials. The ultimate goal of these studies would be a single-phase material exhibiting a strong coupling between inherent ferromagnetic and ferroelectric ordering at room temperatur...
متن کاملResonant Polarization Spectroscopy for Hot X-ray Plasmas
X-ray line polarization spectroscopy is a method of choice for probing hot plasma conditions. The precise roles of resonant structures in this method have not been realized and fully understood. With a sophisticated relativistic close coupling Dirac R-matrix calculation of polarized radiation of the quadrupole magnetic M2 line at 2.717 Å in Ba, we revealed the nature of resonant structures in x...
متن کاملAbsence of orbital currents in superconducting YBa2Cu4O8 using a zeeman-perturbed nuclear-quadrupole-resonance technique.
Zeeman perturbed nuclear quadrupole resonance was applied to evaluate weak magnetic fields in the context of orbital currents in cuprate superconductors. The magnetic environment of the barium atom in c-axis oriented powder samples of YBa(2)Cu(4)O(8) was investigated in the pseudogap phase at 90 K. No evidence for orbital currents was found: any static and dynamic field must be less than 0.07 a...
