Abstract

The relativistic coupled-clusters method combined with the generalized relativistic effective core potential approach and nonvariational one-center restoration technique is applied to evaluation of parameters of the spin-rotational effective Hamiltonian in lead monofluoride to study the effects of violation of time-reversal invariance (T) and space parity (P) in PbF. The obtained hyperfine structure constants, A||=9942 MHz and A=7174 MHz, are stable with respect to the improvement of the correlation treatment, and they are in very good agreement with the experimental data, A||=10147 MHz and A=7264 MHz [R.

Skripnikov, A. V. Titov, and R. J. Mawhorter, Phys. Rev. A 88, 010501(R) (2013)]. This is essential to the important task of verifying the value of effective electric field Eeff=40 GV/cm, the parameter of P-odd interaction WP=1213 Hz, and the parameter of T,P-odd pseudoscalar-scalar electron-nucleus interaction WT,P=91 kHz, which are of primary interest in the Brief Report.
