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".

Observation of the 87Rb 5S1/2 to 4D3/2 electric quadrupole transition at 516.6 nm mediated via an optical nanofibre [PDF]
New Journal of Physics, 2020 Light guided by an optical nanofibre has a very steep evanescent field gradient extending from the fibre surface. This gradient can be exploited to drive electric quadrupole transitions in nearby quantum emitters.

Electric quadrupole transition probabilities for atomic lithium
Atomic Data and Nuclear Data Tables, 2014 Electric quadrupole transition probabilities for atomic lithium have been calculated using the weakest bound electron potential model theory (WBEPMT). We have employed numerical non-relativistic Hartree–Fock wavefunctions for expectation values of radii and the necessary energy values have been taken from the compilation at NIST.

Lamb Dip of a Quadrupole Transition in H_{2}. [PDF]
Physical Review Letters, 2023 The saturated absorption spectrum of the hyperfineless S(0) quadrupole line in the (2-0) band of H_{2} is measured at λ=1189 nm, using the NICE-OHMS technique under cryogenic conditions (72 K).

Control of an Atomic Quadrupole Transition in a Phase-Stable Standing Wave. [PDF]
Physical Review Letters, 2022 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.

Transfer of angular momentum of guided light to an atom with an electric quadrupole transition near an optical nanofiber [PDF]
Physical Review A, 2022 We study the transfer of angular momentum of guided photons to a two-level atom with an electric quadrupole transition near an optical nanofiber. We show that the generation of the axial orbital torque of the driving guided field on the atom is governed by

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 ...
