Fine- and Hyperfine Structure Analysis of the Odd Configurations in the Lead Atom

摘要

The fine- and hyperfine structure (hfs) analysis, on the basis of available experimental data, for the configuration 6s exp 2 6p6d+6s exp 2 6p7s + 6s exp 2 6p8s in PbI has been performed. The Slater integrals, spin-orbit parameters and the effective hfs one-electron parameters have been determined. We find an off-diagonal core-polarization effect in the 6p6d+6p7s - space. Using the calculated radial parameters, the values of the quadrupole for stable and radioactive Pb-nuclei have been determined from measured B-factors of the 6p7s exp 3 P sub 1 state. In addition, a repulsion effect on the hfs sublevels with the same quantum number F has been investigated. (ERA citation 09:044930)
