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 and space parity in PbF. The obtained hyperfine structure constants, MHz and MHz, are stable with respect to the improvement of the correlation treatment, and they are in very good agreement with the experimental data, MHz and 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 GV/cm, the parameter of -odd interaction Hz, and the parameter of -odd pseudoscalar-scalar electron-nucleus interaction kHz, which are of primary interest in the Brief Report.
