New pattern in regular nuclei based on their experimental quadrupole transition rates and some new candidates [PDF]
Scientific Reports, 2023 In this paper, we tried to get a new signature of regular nuclei based on their quadrupole transition rates. We have analyzed the experimental electric quadrupole transition probabilities of well-known "regular nuclei".

Enhanced microwave-atom coupling via quadrupole transition-dressed Rydberg atoms
Frontiers in PhysicsThe power broadening of a coupling laser can be converted into two-photon detuning by electromagnetically induced transparency (EIT), resulting in a residual Doppler effect.

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 ...

Enhancement of specular behavior in atom mirrors with quadrupole-active transitions
Alexandria Engineering Journal, 2023 Modern studies have confirmed the possibility of making atomic mirrors using quadrupole-active atomic transition evanescent waves. The reflection process has been shown to be enhanced to approach specular behavior in several ways.

Enhanced quadrupole effects for atoms in surface spiral beams with a thin dielectric waveguide
Alexandria Engineering Journal, 2022 Recently, some physical research has recognized the coupling of optical phase singularity light with quadrupole-active atomic transitions. We show that a Laguerre-Gaussian beam, when completely internally reflected at the dielectric/vacuum interface, can

Systematic Projected Shell Model Study of Even-Even Dysprosium Isotopes
Atom Indonesia, 2022 Back-bending phenomenon is one of the important phenomena usually seen at high spin states of even - even heavy nuclei. As a result, any changes in the behavior of nuclear rotation, such as increase in moment of inertia versus rotational frequency can be
