Abstract
We report ab initio relativistic correlation calculations of potential curves and spectroscopic constants for the four lowest-lying electronic states of lead monofluoride. We also calculated parameters of the spin-rotational Hamiltonian for the ground and the first excited states including P,T-odd and -odd terms. In particular, we have obtained hyperfine constants of the nucleus. For the state, MHz, MHz and for the state, MHz, MHz. Our values of the ground-state hyperfine constants are in good agreement with previous theoretical studies. We discuss and explain seeming disagreement with the recent experimental data of the sign of the constant . The effective electric field on the electron , which is important in the planned experiment for searching for the electric dipole moment of the electron, is found to be .
