Study of the Electric Quadrupole Moments for some Scandium Isotopes Using Shell Model Calculations with Different Interactions

open access: yesمجلة بغداد للعلوم, 2018
The electric quadrupole moments for some scandium isotopes (41, 43, 44, 45, 46, 47Sc) have been calculated using the shell model in the proton-neutron formalism.

Photoassociation of a cold atom-molecule pair: long-range quadrupole-quadrupole interactions [PDF]

open access: yes, 2010
The general formalism of the multipolar expansion of electrostatic interactions is applied to the calculation the potential energy between an excited atom (without fine structure) and a ground state diatomic molecule at large separations.

Spectral properties of a tractable collective Hamiltonian

open access: yes, 2008
The spectral properties of a tractable collective model Hamiltonian are studied. The potential energy is truncated up to quartic terms in the quadrupole deformation variables, incorporating vibrational, $\gamma$-independent rotational and axially ...

Effect of dipole-quadrupole Robinson mode coupling upon the beam response to radio-frequency phase noise

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2006
In an electron storage ring, coupling between dipole and quadrupole Robinson oscillations modifies the spectrum of longitudinal beam oscillations driven by radio-frequency (rf) generator phase noise. In addition to the main peak at the resonant frequency

Resonance interaction between two entangled gravitational polarizable objects

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We investigate the resonance quadrupole-quadrupole interaction between two entangled gravitationally polarizable objects induced by a bath of fluctuating quantum gravitational fields in vacuum in the framework of linearized quantum gravity.
