All available experimental data on the spectrum of singly ionized carbon have been critically analyzed. Measurement uncertainties of all published studies have been re-assessed. The scope of observational data includes laboratory emission spectra of

Recent advance in calculations of energy levels of the 1s2$l$2$l^{\prime}$ core-excited states for ions along the Li isoelectronic sequence from carbon to uranium suggested that theoretical predictions for the 1s2$l$2$l^{\prime}$ transitions are sign

This work presents 97 remeasured Fe V wavelengths (1200 \r{A} to 1600 \r{A}) and 123 remeasured Ni V wavelengths (1200 \r{A} to 1400 \r{A}) with uncertainties of approximately 2m\r{A}. An additional 67 remeasured Fe V wavelengths and 72 remeasured Ni

In this study we report on high-precision laboratory measurements of transition wavenumbers for 172 atomic sulfur lines in the infrared region 800–11,000 cm ^−1 using Fourier transform spectroscopy techniques. Our analysis includes 96 lines that

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

The measured radiative rates of the 2s22p2 3P1,2 - 2s2p3 5S{\deg}2 intercombination transitions in neutral carbon reported in the literature are critically evaluated by comparing them with theoretical and semi-empirical results. The experimental and

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 astr
