Most of the quadrupole magnets in the KEK B-factory are accompanied by a set of vertical and horizontal dipole corrector magnets in both the LER and HER rings[1]. The typical separation between a quadrupole and a dipole corrector magnet is 202 mm, as measured from the laminated ends. This corresponds to ~3.7 (2.4) times of the bore radius of a quadrupole magnet in the arc (straight) sections. S...

The scattering of the temperature anisotropy quadrupole by free electrons in galaxy clusters leads to a now well-known polarization signal in the cosmic microwave background fluctuations. Using multifrequency polarization data, one can extract the temperature quadrupole and separate it from the contaminant polarization associated with the kinematic quadrupole due to the transverse motion of clu...

We study gravitational lensing by quadrupole potentials within the linearized gravity approximation and the integration over the unperturbed photon trajectory. It is well known that the quadrupole potential contribution to the deviation angle is much smaller than that of the monopole one. We show, however, that quadrupole potentials can change the photon polarization vector, but there is no con...

density functional theory (dft) based calculations have been performed to examine the relaxations of tautomers of 4–hydroxy–6–methylpyridin–2(1h)–one (mpo), as a representative of pyridinone derivatives, at the fullerene (c60) surfaces. optimized molecular properties including energies, dipole moments and atomic scale quadrupole coupling constants (cq) have been evaluated to investigate the str...

We report a comprehensive dataset of beyond-Voigt line-shape parameters (pressure broadening and shift coefficients, their speed-dependences, the complex Dicke parameters) for all electric dipole quadrupole transitions within ground electronic state in He-perturbed HD that are present HITRAN database. The determined from generalized spectroscopic cross-sections which we obtain by solving ab ini...

The nuclear quadrupole moment of In has been determined by combining the experimental nuclear quadrupole coupling constants and electric field gradients, calculated at the four-component CCSD~T! level of theory, of four indium halides. Our recommended value for the nuclear quadrupole moment of In is 770~8! millibarn. A basis set study at the Dirac–Hartree–Fock level shows a slow convergence of ...
