This compilation revises the 1991 listing of atomic data for the lighter elements from
hydrogen to gallium. The tabulation emphasizes resonance lines, ie, lines whose lower level …

The CHIANTI atomic database contains atomic energy levels, wavelengths, radiative
transition probabilities, and collisional excitation data for a large number of ions of …

As a contribution to the International Opacity Project, large numbers of multiplet term
energies, f-values and photoionization cross sections have been calculated for those Mg …

Transition probability of the AL II 2669 intersystem line ADS Classic is now deprecated. It will be
completely retired in October 2019. This page will automatically redirect to the new ADS …

MultiConfiguration Dirac-Hartree-Fock (MCDHF) and relativistic configuration interaction
(RCI) calculations were performed for 28 and 78 states in neutral and singly ionized …

Detailed models of the chromospheres of several 'hybrid'bright giants are presented. The
models extend from the base of the chromosphere and into the transition area. These …

We review recent calculations of oscillator strengths for medium to heavy ions in which the
influence of the core on the valence electrons has been treated by the use of model …

The 2p-subshell photoabsorption spectrum of Mg-like silicon has been recorded for the first
time using the dual laser plasma (DLP) technique. The spectrum is discussed within a …

The R-matrix method is used to calculate the collision strengths for 35 intercombination
transitions in Al II. Configuration interaction wavefunctions are used to represent the twelve …

Relative intensity measurements of Al I and Al II spectral lines in the visible and ultraviolet
spectral ranges are performed using a capacitively coupled high frequency double hollow …
