Theoretical Description of Energy Spectra and Quadrupole Transition Probabilities of 190 Hg

open access: yesCumhuriyet Science Journal, 2018
In this paper, we have considered thecoexistence of two quite different structures, the deformed and sphericalshapes in 190Hg nucleus. To this aim, we have determined the energyspectra and quadrupole transition probabilities of this nucleus.

Generate localized optical vortices by quadrupole transition and twisted light

open access: yesJournal of Taibah University for Science, 2021
We explain how quadrupole-active atomic interactions be able to be enhanced once the neutral atom interacts with an evanescent winding light modes.

Collective Quadrupole Excitations in Transitional Nuclei [PDF]

open access: yesPhysica 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 ...

Ωcγ→Ωc⁎ transition in lattice QCD

open access: yesPhysics Letters B, 2015
We study the electromagnetic Ωcγ→Ωc⁎ transition in 2+1 flavor lattice QCD, which gives access to the dominant decay mode of Ωc⁎ baryon. The magnetic dipole and the electric quadrupole transition form factors are computed.

Coherent Excitation of the 6S1/2 to 5D3/2 Electric Quadrupole Transition in 138Ba+ [PDF]

open access: yes, 2012
The electric dipole-forbidden, quadrupole 6S1/2 5D3/2 transition in Ba+ near 2051 nm, with a natural linewidth of 13 mHz, is attractive for potential observation of parity non-conservation, and also as a clock transition for a barium ion optical ...

Quadrupole moments of odd-A 53−63Mn: Onset of collectivity towards N=40

open access: yesPhysics Letters B, 2016
The spectroscopic quadrupole moments of the odd–even Mn isotopes between N=28 and N=38 have been measured using bunched-beam collinear laser spectroscopy at ISOLDE, CERN.

Microscopic description of quadrupole-octupole coupling in Sm and Gd isotopes with the Gogny Energy Density Functional [PDF]

open access: yes, 2012
The interplay between the collective dynamics of the quadrupole and octupole deformation degree of freedom is discussed in a series of Sm and Gd isotopes both at the mean field level and beyond, including parity symmetry restoration and configuration ...

Valence quark contribution for the gamma N -> Delta quadrupole transition extracted from lattice QCD [PDF]

open access: yes, 2009
Starting with a spectator quark model developed for the nucleon (N) and the Delta in the physical pion mass region, we extend the predictions of the reaction gamma N -> Delta to the lattice QCD regime.

Moments of the neutron charge form factor and the N --> Delta quadrupole transition. [PDF]

open access: yesPhysical Review Letters, 2001
Recent data allow a new parametrization of the neutron charge form factor GnE. A parameter-free quark-model relation between GnE and the N-->Delta quadrupole form factor G(N-->Delta)C2 is used to predict G(N-->Delta)C2 from GnE data.

Abnormal field-dependence of magnetocaloric effect in ErB4 and TmB4

open access: yesAIP Advances, 2020
The coupled system of multi-degrees of freedom, such as charge, spin, orbital and lattice, has recently received much attention due to its potential to improve the magnetocaloric effect (MCE).
