Empirical regularities for excitation cross-sections of lead atom (radiative transitions from even levels)

Abstract

Excitation of even levels of lead atoms was studied using the method of extended crossing beams with recording of optical signal emitted by excited atoms. Fortyeight excitation cross sections have been measured at an incident electron energy of 50 eV. Four optical excitation functions (OEFs) have been recorded under varying electron energies in the range E = 0-200 eV. The cross-sections obtained have been used to examination of empirical regularities in the behavior of excitation cross-sections, including those of perturbed series.

Empirical regularities in the excitation cross-section behavior of the lead atom (transitions from energy levels of 6pndconfigurations)

“…However, the paucity of findings has so far hampered investigation into the regularities in excitation cross-section behavior of the lead atom. Only a recent publication (Smirnov 2016b) did address serial regularities of transitions originating at even levels of the lead atom from an experimental angle of sight.…”
