Calcium and Potassium Spectra in the EUV
Atoms, 2020 In online data bases, the entries on extreme ultraviolet (EUV) spectra of Ca are much more sparse than those of neighbouring elements such as Ar, K, Sc and Ti.

Validation of computed extreme ultraviolet emission spectra during solar flares
Earth, Planets and Space, 2021 X-rays and extreme ultraviolet (EUV) emissions from solar flares rapidly change the physical composition of the Earth’s thermosphere and ionosphere, thereby causing space weather phenomena such as communication failures.

Extreme-Ultraviolet Beam-Foil Spectra of Na through Cl
Atoms, 2021 Beam-foil EUV spectra of elements from Na through Cl are presented, partly in survey spectra and partly in detail spectra. The ionization stages of interest are medium to high, so that three to thirteen electrons remain.

Coherent control of extreme ultraviolet emission generated through frustrated tunneling ionization
New Journal of Physics, 2022 Coherent extreme ultraviolet (EUV) line emissions can be generated from an atom excited through frustrated tunneling ionization (FTI). The phase variation of the EUV emission in a generation medium along the propagation direction is a critical parameter ...

Delayed response of the global total electron content to solar EUV variations [PDF]
Advances in Radio Science, 2016 The ionospheric response to solar extreme ultraviolet (EUV) variability during 2011–2014 is shown by simple proxies based on Solar Dynamics Observatory/Extreme Ultraviolet Variability Experiment solar EUV spectra.

Retrieving the solar EUV spectrum from a reduced set of spectral lines [PDF]
Annales Geophysicae, 2005 The solar EUV irradiance is a key input for thermospheric and ionospheric models. Difficulties in continuously measuring the calibrated spectrum has prompted the use of various surrogate quantities.
