Spectrum of Ni V in the Vacuum Ultraviolet

November 27, 2019
Author(s)
Jacob W. Ward, A J. Raassen, Alexander Kramida, Gillian Nave
This work presents 97 remeasured Fe V wavelengths (1200 Å to 1600 Å) and 123 remeasured Ni V wavelengths (1200 Å to 1400 Å) with uncertainties of approximately 2 mÅ. An additional 67 remeasured Fe V wavelengths and 72 remeasured Ni V wavelengths with

Cowan code: 50 years of growing impact on atomic physics

July 2, 2019
Author(s)
Alexander Kramida
The famous Cowan's book "The Theory of Atomic Structure and Spectra" published in 1981 and his suite of computer codes based on it continue to be highly influential in atomic physics and many other researchareas. As of September 2018, there are more than

Revision of the ionization energy of neutral carbon

May 22, 2018
Author(s)
W L. Glab, Haris Kunari, Alexander Kramida
This publication describes a re-analysis of previously published data on neutral carbon (C I) utilizing critically examined and improved values for the line energies of the absorption spectrum of molecular iodine to calibrate the transition energies of C I

CRITICALLY EVALUATED SPECTRAL DATA FOR NEUTRAL CARBON (C I)

November 22, 2017
Author(s)
Haris Kunari, Alexander Kramida
In this critical compilation, all known to us experimental data on the spectrum of neutral carbon were methodically evaluated and supplemented by parametric calculations with Cowan's code. The sources of experimental data vary from laboratory to

Radiative rates of transitions from the 2s2p3 5Sdeg2 state in neutral carbon

November 1, 2017
Author(s)
Alexander Kramida, Haris Kunari
The measured radiative rates of the 2s22p2 3P1,2 – 2s2p3 5S°2 intercombination transitions in neutral carbon reported in the literature are critically evaluated in comparison with theoretical results. The experimental and theoretical values are compared

The Cu II Spectrum

February 24, 2017
Author(s)
Alexander Kramida, Gillian Nave, Joseph Reader
New wavelength measurements in the vacuum ultraviolet (VUV), ultraviolet and visible spectral regions have been combined with available literature data to refine and extend the description of the spectrum of singly ionized copper (Cu II). In the VUV region
