Stark broadening parameter tables for neutral zinc spectral lines [PDF]
Serbian Astronomical Journal, 1999 Using a semiclassical approach, we have calculated electron−, proton− and He II−impact line widths and shifts for 32 Zn I multiplets as a function of temperature and perturber density.

Advanced Functional Materials, EarlyView.This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

The Astrophysical JournalNeutron star surfaces have extremely high magnetic fields. In the atmosphere, the broadening of spectral lines will be substantial from the dense plasma as well as from the magnetic field.

Atoms, 2021 The present paper revisits the determination of the semi-classical limit of the Feshbach resonances which play a role in electron impact broadening (the so-called “Stark“ broadening) of isolated spectral lines of ionized atoms. The Gailitis approximation

Optimised control of Stark-shift-chirped rapid-adiabatic-passage in a lambda-type three-level system
, 2009 Inhomogeneous broadening of energy levels is one of the principal limiting factors for achieving "slow" or "stationary" light in solid state media by means of electromagnetically induced transparency (EIT), a quantum version of stimulated Raman adiabatic

Nucleation‐Controlled Reconstruction of CuOx for Selective CO2 Electroreduction
Advanced Functional Materials, EarlyView.The ratio of oxygen vacancies (Ov) and exposed Cu2O (111)/(200) of CuOx precatalyst is modulated by nucleation control of Cu(OH)2 precursor. Low Ov ratio and high ratio of Cu2O (111)/(200) in slow‐nucleated CuOx reconstructs to high‐coordinated oxide‐derived copper (OD‐Cu) during electrochemical CO2 reduction reaction (CO2RR) and exhibits enhanced ...

Stark broadening data tables for some analogous spectral lines along Li and Be isoelectronic sequences [PDF]
Serbian Astronomical Journal, 1999 By using the semiclassical perturbation approach, Stark broadening parameters due to the interaction with a selection of perturbers of interest for recently published experimental results for Li - like B III, C IV, N V and O VI 3s2S-3p2Po, and ...

Methods for Line Shapes in Plasmas in the Presence of External Electric Fields
Atoms, 2021 Line broadening is usually dominated by interactions of an atomic system with a stochastic, random medium. When, in addition to the random medium, a non-random field (such as a laser) is applied, the line profile may be modified in significant ways.

Gradient Echo Quantum Memory for Light using Two-level Atoms
, 2007 We propose a quantum memory for light that is analogous to the NMR gradient echo. Our proposal is ideally perfectly efficient and provides simplifications to current 3-level quantum memory schemes based on controlled inhomogeneous broadening.

Advanced Functional Materials, EarlyView.Ru single atoms and RuP nanoclusters are co‐anchored in N, P, and B co‐doped porous carbon nanospheres via in situ carbonization/phosphidation of a boronate polymer precursor. RuP activates water, while nearby Ru single atoms accelerate H2 formation through H* transfer. The catalyst delivers low overpotential and high durability in alkaline HER and AEM
