MEASUREMENT AND INTERPRETATION OF THE ODD-PARITY LEVELS OF PB I

摘要: We consider 51 odd-parity configurations of Pb i utilizing all data available from absorption and emission spectroscopy measurements, photoionization experiments, ejected-electron spectroscopy. These include detailed results our earlier laser spectroscopic studies the 6${\mathit{s}}^{2}$6pns, 6${\mathit{s}}^{2}$6pnd, 6${\mathit{s}}^{2}$6png Rydberg levels [P. Buch, J. Nellessen, W. Ertmer, Phys. Scr. 38, 664 (1988)]. The analysis has been performed with aid a linked-parameter method level-fitting calculations in large multiconfiguration basis. New identifications 6s6${\mathit{p}}^{3}$ are proposed reasons for their assignment presented. On basis precise assignments 242 electronic energy given. Eigenvectors obtained these can be used to calculate values other physical observables high precision. In addition, we have also made appropriate pseudorelativistic Hartree-Fock ab initio level structure, oscillator strengths, autoionization widths procedural guidance comparison purposes.
