A-values + oscillator strength of Ca XIII
Listed in IVOA Registry (Virtual Observatory)
Electron impact collision strengths, energy levels, oscillator strengths and spontaneous radiative decay rates are calculated for Ca XIII.
Description
The configurations used are 2s2.2p4, 2s.2p5, 2p6, 2s2.2p3.3s, 2s2.2p3.3p and 2s2.2p3.3d giving rise to 86 fine-structure levels in intermediate coupling. Collision strengths are calculated at five incident energies (40, 80, 120, 160 and 200Ry) in the distorted wave approximation.
Excitation rate coefficients are calculated as a function of electron temperature by assuming a Maxwellian electron velocity distribution. Using the excitation rate coefficients and the radiative transition rates, statistical equilibrium equations for level populations are solved at electron densities covering the range of 10^8-10^14cm^-3 at an electron temperature of logTe(K)=6.5, corresponding to maximum abundance of Ca XIII.

Relative and absolute spectral line intensities are calculated, and their diagnostic relevance is discussed. This dataset will be made available in the next version of the CHIANTI database.
