Evaluation of rare gas transition probabilities

Full text: Transition probabilities together with the cross sections of excitation by electron collisions are the main parameters in the definition of the line intensity within each ionization stage. Our interest is in the Ar and Xe ions. Energy levels, wavelengths and radiative transitions probabilities have been calculated using two different numerical codes: SuperSTructure (SST) developed by Eissner and collaborators, and the Flexible Atomic Code (FAC) developed by Gu. The multiplet spectra of Xe II are presented as an example (5p-5d, 5p-6s, 6s-6p), and are compared with the results obtained by the CbA code based on the Coulomb Approximation developed by Katsonis, and with the equivalent data obtained by the Cowan Atomic Code (CATS).
