Description

We use a multiconfiguration Dirac-Fock code [1,2] to calculate electronic excitation cross sections and radiative decay transition probabilities for a large number of atomic levels in Pm-like bismuth. By numerically solving a set of equilibrium equations we were able to obtain the level populations of the 4f145s, 4f135s5f, 4f135s5d, 4f135s5p, and 4f135s2 configurations and synthesized spectra for a number of electronic density values in an EBIT for 640 keV incident electron energy.

The synthesized spectrum we obtained for 1010 cm3 electronic density agrees qualitatively with the experimental data of Kobayashi et al. [3]. We found significative differences between our simulations and Kobayashi’s for several electronic density values.

The emission lines position and relative intensity can also be compared with laser produced plasma spectra, to improve the identification of the Pm-like ions and provide experimental values of electron density at those plasma conditions.
