Electric quadrupole transitions in carbon dioxide [PDF]
The Journal of Chemical Physics, 2021 Recent advances in high sensitivity spectroscopy have made it possible, in combination with accurate theoretical predictions, to observe, for the first time, very weak electric quadrupole transitions in a polar polyatomic molecule of water. Here, we present accurate theoretical predictions of the complete quadrupole rovibrational spectrum of a non ...

Quadrupole transitions in 20Ne
Physics Letters B, 1978 Abstract Untruncated shell model calculations in the 1s-0d shell using Chung-Wildenthal effective interactions have been performed for 20 Ne and the electron scattering form factors for elastic scattering and for the excitation of 2 1 + , 2 1 + and 2 3 + states have been examined.

Electric quadrupole transitions in Ni XVIII [PDF]
Astronomy and Astrophysics Supplement Series, 2000 Relativistic Quantum Defect Orbital (RQDO) calculations have been performed in the LS coupling scheme on electric quadrupole (E2) transitions between levels belonging to several astrophysically important con- gurations of Ni XVIII. A number of line strengths are reported and compared with the ones found in the litera- ture.

Collective Quadrupole Excitations in Transitional Nuclei [PDF]
Physica Scripta, 2000 The generalized Bohr Hamiltonian was used to describe the low-lying collective excitations in even-even isotopes of Ru, Pd, Te, Ba and Nd. The Strutinsky collective potential and cranking inertial functions were obtained using the Nilsson potential. The effect of coupling with the pairing vibrations is taken into account approximately when determining ...

Infrared extrapolations of quadrupole moments and transitions
Physical Review C, 2016 We study the convergence of bound-state quadrupole moments in finite harmonic oscillator spaces. We derive an expression for the infrared extrapolation for the quadrupole moment of a nucleus and benchmark our results using different model interactions for the deuteron.

Control of an Atomic Quadrupole Transition in a Phase-Stable Standing Wave
Physical Review Letters, 2023 Using a single calcium ion confined in a surface-electrode trap, we study the interaction of electric quadrupole transitions with a passively phase-stable optical standing wave field sourced by photonics integrated within the trap. We characterize the optical fields through spatial mapping of the Rabi frequencies of both carrier and motional sideband ...

Dynamical Interplay of Pairing and Quadrupole Modes in Transitional Nuclei. I [PDF]
Progress of Theoretical Physics, 1979 Using the single j-shell model with the pairing plus quadrupole force, we show that l) the transition from vibrational to rotational excitation structure can be reproduced within the collective model space built up from the J =0- and J =2- coupled nucleon pairs, 2) change of the monopole pair field due to many-quasiparticle excitations does accelerate ...
