Abstract

We report first configuration interaction calculations of hyperfine constants A and the effective electric field Wd acting on the electric-dipole moment of the electron, in two excited electronic states of Pb207O. A combined scheme of correlation calculations is also developed and applied to studying the core properties. The obtained hyperfine constants, A=3826MHz for the a(1) state and A=4887MHz for the B(1) state, are in very good agreement with the experimental data, 4113MHz and 5000±200MHz, respectively. We find Wd=(6.10.6+1.8)×1024Hz(ecm) for a(1), and Wd=(8.0±1.6)×1024Hz(ecm) for B(1).
